The North Korean delegation is headed by Workers Party secretary for international affairs Kim Yong-sun. The US delegation is lead by Undersecretary of State for Political Affairs Arnold Kanter. Kanter’s “talking points” have been approved in advance by a US State Department interagency committee, as well as by the South Korean and Japanese governments. These points include urging North Korea to permit IAEA inspections and to give up its nuclear weapons option. North Korea responds by agreeing to sign the IAEA safeguards agreement.

Don Oberdorfer, The Two Koreas: A Contemporary History, (Reading, MA: Addison-Wesley, 1997), pp.266-267.

30 January 1992

North Korea signs the IAEA safeguards agreement. North Korea’s Deputy Minister for the atomic energy industry Hong Gun-pyo says that North Korea will abide by the agreement fully. It should be noted however, that North Korea does not ratify nor implement the agreement at this time. North Korea’s director of the foreign ministry Chang Mun-son says that the process of ratification by the legislature could take as long as six months.

The IAEA inspections process comprises four distinct phases. The first requires North Korea to submit an official report of its existing nuclear facilities. During the second phase, the IAEA will conduct a series of ad hoc inspections to verify the aforementioned list, as well as gather some initial data about the nuclear program. Third, North Korea and the IAEA will sign various subsidiary agreements and attachments to the accord describing inspection procedures for specific facilities. And fourth, the IAEA will begin routine inspections designed to ensure that the nuclear facilities are not being used for military purposes.

February 1992

The German Federal Intelligence Service (BND), the West German intelligence agency, is investigating reports that the West German company, Leybold A.G. supplied North Korea with two electron beam furnaces, two “laboratory furnaces,” and a “small laboratory furnace.” It is suspected that the first four furnaces were shipped to North Korea via India or Pakistan and that the “small laboratory furnace” was shipped via former East Germany. The furnaces could be used in North Korea’s nuclear weapons program. The BND also suspects that a Leybold employee recently went to North Korea to work on a nuclear facility.

Nuclear Engineering International, February 1992, pp.7-8.

February 1992

According to US intelligence reports, North Korea has built deep tunnels around its nuclear facility at Yongbyon. The tunneling appears to be an effort to protect the facility from possible attacks by the United States and South Korea. It may also be a means of hiding nuclear weapons from international inspectors. South Korean reports published in 1991 say that North Korea built similar tunnels to protect a suspected nuclear site near Sinpo.

Bill Gertz, Washington Times, 21 February 1991, p.A9.

February 1992

North and South Korea agree to form the JNCC by 19 March 1992. The purpose of the committee is to oversee the mutual nuclear inspections.

Newsweek, 9 March 1992.

February – April 1992

The North Korean Standing Committee agrees that the safeguards agreement should be ratified. According to North Korean Ambassador O Chang-rim, North Korea will use and develop nuclear energy “in company with hydro and thermopower to meet increasing demand for electricity [and has] pursued necessary research and preparations for its realization.” He says that North Korea’s nuclear program is entirely peaceful.

Gamini Senevirtne, Nucleonics Week, 27 February 1992, p.6.

20 February 1992

South Korean Prime Minister Chung Won-shik meets with North Korea Prime Minister Yon Hyong-muk to exchange agreements on the creation of a nuclear-weapons-free Korean Peninsula. Chung indicates that it is necessary for North Korea to produce more evidence that its nuclear intentions are peaceful.

During the meeting North Korean President Kim Il-sung ignores the South Korean demand for mutual nuclear inspections to take place at an early date. Kim also dismisses Western reports that North Korea is close to constructing a nuclear bomb. (The reports that he is referring to say that North Korea may be able to produce weapons-grade nuclear material by summer 1992.) Kim says that North Korea does not intend to enter into a nuclear arms race with its neighbors and furthermore, that it is unimaginable for his country “to develop nuclear weapons that can wipe out the Korean people.” The matter will be discussed in greater detail during talks scheduled for the spring of 1992 between North Korean President Kim Il-sung and South Korean President Roh Tae-woo.

25 February 1992

CIA Director Robert M. Gates testifies before the US House Foreign Affairs Committee that once North Korea has sufficient fissionable material, it will only be a matter of a few months before it will be capable of building a nuclear weapon. He also testifies that North Korea appears to be focused solely on building a reprocessing plant and producing weapons-grade plutonium. However, senior officials at the US State Department and Pentagon say that Gates’ prediction is too “harsh” and that North Korea would need at least two more years to acquire a nuclear weapons capability.

Rupert Cornwell, Independent (London), 26 February 1992, p.10.

26 February 1992

The IAEA Board of Governors reaffirms its right to conduct special inspections of undeclared nuclear sites. It says that inspections will only occur on “rare occasions.” The IAEA has not yet performed such an inspection. IAEA spokesman David Kyd announces that the Board has agreed on a plan that requires all nations with full-scope safeguards agreements to begin submitting preliminary designs of nuclear facilities to the IAEA once the decision to construct them is made. At its next meeting in June 1992, the Board will discuss a plan for mandatory reporting of imports and exports of nuclear material and sensitive non-nuclear equipment.

Michael J. Wise, Washington Post, 27 February 1992, p.A33.

Gerald F. Seib, Wall Street Journal, 9 March 1992, p.A10.

9 March 1992

North Korea’s delay in ratifying the IAEA safeguards agreement creates suspicions that it is either buying time to produce weapons-grade plutonium or hiding plutonium before the inspections begin. The United States is reluctant to seriously consider plans for a military strike against North Korea’s nuclear weapons facilities.

Gerald F. Seib, Wall Street Journal, 9 March 1992, p.A10.

14 March 1992

North and South Korea conclude an agreement to establish (1) the JNCC, and (2) inspections of nuclear facilities in early-June 1992. The inspections agreement, however, does not hold North Korea to a strict schedule, and does not mention specific nuclear facilities in North Korea (e.g., Yongbyon). According to Article 3 of the agreement, the JNCC’s first meeting will be held in Panmunjom on 19 March 1992. Article 4 states that the Koreas will “jointly try to adopt the necessary documents for verifying nuclear-free status of the Korean Peninsula within approximately two-months time” after 19 March 1992. Once this document has been signed, the Koreas agree that inspections will begin within 20 days.

16 March 1992

Japanese press reports quote a 14 March 1992 issue of the Russian weekly Argumenty i Fakty, which states that North Korea developed a bomb trigger at the Yongbyon plant more than a year ago. The information was derived from a classified 8 February 1992 KGB document that was sent to the Central Committee of the Soviet Communist Party by General Vladimir Kryuchkov, chair of the Committee for State Security. The information was also relayed to the Kremlin, which chose to take no action against North Korea. The report also states that North Korean President Kim Il-sung is personally in charge of North Korea’s nuclear program and wants to make North Korea a nuclear power. North Korea has not conducted any nuclear tests because it wants to keep its nuclear capability secret from the international community.

Edward Neilan, Washington Times, 16 March 1992.

16 March 1992

In reference to North and South Korean mutual inspections, as stipulated under the December 1991 nuclear-weapons-free-zone agreement, a South Korean unification ministry official says that, “If everything goes smoothly, mutual inspections will take place” around 10 June 1992.

Lee Su-wan, Reuters, 16 March 1992.

18 March 1992

The United States informs North Korea that it will impose sanctions if North Korea does not allow international inspections of its nuclear facilities. The United States and South Korea believe that North Korea is stalling inspections in order to move its nuclear facilities underground. According to the United States, several convoys of trucks have left Yongbyon.

Daily Telegraph (London), 18 March 1992, p.A3.

18 March 1992

South Korean Foreign Minister Yi Sang-ok requests Russian Foreign Minister Andrei Kozyrev to pressure North Korea to open its nuclear facilities to inspection. Based on Russia’s desire to see the North and South refrain from developing nuclear weapons, Kozyrev agrees to assist South Korea. Kozyrev says that reports alleging that North Korea possesses nuclear detonators are false.

Maxim Yusin, Izvestiya (Moscow), 20 March 1992, p.3; Reuters, 18 March 1992.

19 March 1992

North and South Korea conduct the first JNCC meeting. The purpose of the meeting is to develop “a specific plan for proposed mutual inspections of suspected nuclear weapons sites.” However, little progress is made. North Korea says that the agreements signed with the South are merely statements of intent and are therefore not binding. Despite the announcement, South Korea advocates regular bilateral inspections of nuclear sites four times a year with twelve special inspections annually. Draft proposals for inspections plans will be considered before the next JNCC meeting, which is scheduled for 1 April 1992 in Panmunjom.

1 April 1992

During the second JNCC meeting, North and South Korea fail to reach an agreement on inspections proposals. South Korea proposes that regular inspections be conducted on nuclear materials and facilities at least 16 times a year, and that special inspections be conducted on military bases at least 40 times a year. South Korea also requests that equal numbers of facilities be inspected by both parties. North Korea responds by saying that South Korea should allow inspections of all US bases, but that the only site it will allow to be inspected is the Yongbyon nuclear facility.

Jonah Kaplan, Carnegie Endowment for International Peace, 21 April 1993.

12 April 1992

Korean Central Television (Pyongyang) broadcasts a report in which the deputy director of the Bureau of Scientific Guidance in the Ministry of Nuclear Industry, Yi Yong-ha is interviewed. He emphasizes that North Korea’s nuclear program is based upon peaceful purpose and self-reliance. The program focuses on exploration, development and manufacture of uranium ore concentrate and nuclear fuel rods. Tours of the test nuclear power station and the nuclear fuel rod production plant, and a visit to the Pyongyang Atomic Energy Research Institute are described. The report also mentions that North Korea has future plans of building larger, more powerful nuclear energy reactors.

Korean Central Television (Pyongyang), 12 April 1992.

12 April 1992

North Korean President Kim Il-sung says that North Korea does not possess nuclear weapons and has no intention of doing so given the large nuclear arsenal already held by the “big countries.” He says that North Korea is willing to receive international inspectors at its nuclear facilities and all that needs to be arranged is the procedural formality of informing the IAEA.

Washington Times, 15 April 1992, p.A11.

14 April 1992

According to the head of the North Korean Ministry of Atomic Energy’s Foreign Affairs Bureau, Choe Chong-sun, three nuclear facilities in North Korea will be opened for international inspection. The facilities include a 5MW research reactor built in 1986, and the 50MW and 200MW reactors, which are currently under construction. Choe denies that North Korea has a reprocessing plant. IAEA Director General Hans Blix says that if North Korea does not declare the facility, he will recommend to the IAEA Board of Governors at the 15 June 1992 meeting that the Agency request a UN-sanctioned inspection of the site.

Don Oberdorfer, Washington Post, 6 May 1992, p.A11.

15 April 1992

The North Korean government releases a video showing its 5MW, 30MW, and 200MW nuclear reactors. It is suspected that the 5MW nuclear reactor came on-line in 1986 and was produced indigenously. Officials in the Bush administration warn that North Korea may be months away from building a nuclear weapon. Some officials in Washington have discussed preemptive strikes against identified North Korean nuclear facilities.

T.R. Reid, Washington Post, 17 April 1992, p.A7.

19 April 1992

During the third JNCC meeting, North and South Korea attempt to discuss regulations for mutual inspections. However, no progress is made. South Korea insists that the number of sites inspected for both sides be equal and subject to mutual inspections based on the principle of reciprocity. North Korea, however, says that if Yongbyon is to be opened for inspection, all US military installations in South Korea must be opened for inspection. The two sides are unable to reach an agreement on the date of the next JNCC meeting.

Jonah Kaplan, Carnegie Endowment for International Peace, 21 April 1993.

28 April-4 May 1992

Members of the Carnegie Endowment for International Peace study group meet with the North Korean government and military leaders to discuss North Korea’s nuclear program.

North Korea initially claims that the Yongbyon reactor functioned occasionally. However, after viewing a US satellite picture that depicted the opposite, the North Koreans admit to the IAEA that the reactor has been in constant operation for six years. They also say that the same fuel rod has been used in the core of the reactor for the past six years. According to Leonard Spector, an expert from the Carnegie Endowment, the only way to get a “clear-cut answer” is to conduct a test of the fuel core.

May 1992

An isotope processing plant is discovered in North Korea at Yongbyon.

Jane’s Intelligence Review, Special Report No. 2, p.7.

4 May 1992

Twenty-five days before schedule, North Korea supplies the IAEA with a 150-page “initial report” declaring its nuclear facilities and materials. The report, however, does not list the actual amount of plutonium North Korea has reprocessed at Yongbyon. Rather, it depicts gram quantities of plutonium that were separated in 1990 at an industrial-scale reprocessing facility still under construction. North Korea says that the plutonium was acquired from damaged fuel assemblies at the 5MW research reactor.

Although the IAEA does not release the actual report, it does produce a report stating the facilities and materials North Korea admits to having. This includes: North Korean nuclear material and design information, a research reactor and critical assembly at the Institute of Nuclear Physics (under IAEA safeguards), a sub-critical facility at Kim Il-sung University in Pyongyang, a fuel rod fabrication plant and storage facility at Yongbyon, a 5MW nuclear reactor and a radiochemical laboratory under construction at the Institute of Radiochemistry in Yongbyon, a 50MW nuclear plant under construction in Yongbyon, a 200MW plant under construction in Taechon (in North Pyongan Province), and three planned 635MW nuclear reactors. The radiochemical laboratory is reportedly for research on the separation of uranium and plutonium waste management. It also serves as a technical training center. Two uranium mines and two centers for uranium concentrate production are also listed. This list closely matches Western estimates of the scope of North Korea’s nuclear program.

7 May 1992

As a means of ensuring that the IAEA team does not “miss anything” during inspections, US officials provide IAEA Director General Hans Blix and his top aides intelligence briefings in September 1991, March 1992, and 7 May 1992. During the last briefing, Blix is given a “virtual reality” tour of the Yongbyon nuclear complex. US officials place a great deal of emphasis on the reprocessing facility, which North Korea has identified as a “radiochemical laboratory.”

Don Oberdorfer, The Two Koreas: A Contemporary History, (Reading, MA: Addison-Wesley, 1997), pp.268-269.

11-16 May 1992

IAEA Director General Hans Blix arrives in Pyongyang prior to the IAEA inspection team to meet with North Korean Prime Minister Yon Hyong-muk, Minister of Atomic Energy Choe Hak-kun and first Deputy Minister of Foreign Affairs Kang Sok-ju. He is reassured that the inspectors will be allowed access to any site in North Korea regardless if it is listed in the initial report submitted on 4 May 1992 to the IAEA.

In the course of the meetings, Blix visits the unfinished nuclear reprocessing laboratory at Yongbyon. After seeing the site, he reports that North Korea is building a nuclear fuel reprocessing facility capable of processing spent uranium into plutonium. He says that North Korea has already produced a “tiny quantity” of plutonium. However, the quantity is much less than what is required to build a nuclear weapon. According to the North Koreans, the reprocessing plant will be used to produce mixed-oxide fuel for future fast-breeder reactors. North Korea also expresses interest in building gas-graphite reactors because it can do so indigenously.

Reid, Washington Post, 17 May 1992.

Mid-May 1992

Following a meeting between IAEA Director General Hans Blix and North Korean Prime Minister Yon Hyong-muk and Minister of Atomic Energy Choe Hak-kun, North Korea says that it is willing to consider eliminating certain elements of its nuclear program if foreign countries provide “the required assistance.” Blix says that he is concerned about North Korea’s nuclear program and the possibility that it will develop a nuclear bomb with special emphasis on reprocessing spent reactor fuel into plutonium. Yon denies that North Korea is interested in nuclear weapons. However, he says that North Korea is interested in using modern light-water reactors rather than the heavy-water reactors (whose by-product can be more easily reprocessed to produce plutonium).

Jeffrey Smith, Washington Post, 20 June 1992.

13-15 May 1992

During North Korean-Japanese normalization talks, Japan demands that North Korea immediately implement IAEA inspections. A deadlock in the talks arises from Japanese demands over the reprocessing facility in North Korea. The talks are conducted by North Korean chief negotiator Li Sam-ro and Japanese Ambassador Noboru Nakahira.

Following the talks, IAEA Director General Hans Blix travels to Japan to prepare for the 25 May 1992 inspections of North Korea’s facilities. While in Japan, Blix informs officials that North Korea used hot cells to separate plutonium in 1990. He tells Japanese Science and Technology Minister Kanzo Tanigawa that the IAEA team will verify whether North Korea actually used the cells. North Korean officials have told Blix that the “radiochemical laboratory” was completed in 1987 and that a “very small amount” of plutonium had been separated there. According to Blix, the reprocessing lab that he saw during his earlier visit was missing some equipment. However, no facilities were under construction during his visit.

25 May–7 June 1992

Willi Theis leads the first IAEA inspection team to North Korea. During the inspections of Yongbyon, the team is able to verify the location of fissionable material as stated in North Korea’s “initial report,” which was submitted to the IAEA on 4 May 1992. In doing so, they visit the six-story building the size of two football fields designated as the “radiochemical laboratory.” The team discovers that the building is only 80 percent complete, and that the equipment inside is only 40 percent ready for full-scale production. According to one IAEA official, “the works inside the building are ‘extremely primitive’ and far from ready to produce quantities of plutonium needed for a stockpile of atomic weapons.”

The IAEA team also inspects a 5MW research reactor that came online in 1986, and a 50MW power plant scheduled to become operational by 1996. According to Blix, earlier reports, which stated that there is electrical equipment around the 200MW plant, are false. Rather, he saw “poles on which lines could be mounted.” The North Koreans informed him that they are attempting to develop a civil nuclear power program using natural uranium and graphite.

27 May 1992

During the fifth JNCC meeting, very little progress is made on the issue of mutual inspections. By delaying discussion on inspection guidelines, North Korea blocks any possibility of mutual inspections prior to July 1992. South Korea responds by warning North Korea that delaying talks further could lead to an impasse in inter-Korean exchanges in other areas.

7 June-8 October 1992

During a series of meetings, the United States and South Korea decide not to cancel the Team Spirit military exercises. They also decide to postpone reducing the number of US forces in South Korea. They do so based on “suspicion of nuclear development” in North Korea. North Korea, however, says that the suspicion is unfounded. Team Spirit military exercises were formerly suspended prior to IAEA inspections of North Korean nuclear facilities. North Korea claims that it is unjustifiable to resume the exercises during future inspections.

Nodong Sinmun (Seoul), 13 October 1992.

8 June 1992

According to US State Department spokeswoman Margaret Tutwiler, the United States may provide North Korea with access to advanced nuclear technology if it adheres to international nuclear agreements and safeguards. Tutwiler said she is unaware of reports of North Korea’s offer to stop producing plutonium in exchange for alternative nuclear power technologies from the IAEA, and therefore does not comment on the 1 January 1992 Beijing talks where the offer was allegedly made. The United States believes that it is unnecessary for North Korea to have reprocessing facilities. Furthermore, such facilities are outlawed under the Joint Agreement between North and South Korea.

Nucleonics Week, 11 June 1992, pp.11-12; Yonhap (Seoul), 11 June 1992.

11 June 1992

The United States and South Korea consider North Korea’s request for technical assistance in constructing a light-water reactor. If they do decide to assist North Korea, it will only be on the grounds that North Korea accepts bilateral North-South inspections and abandons its reprocessing activities.

Yonhap (Seoul), 11 June 1992.

13 June 1992

According to the IAEA, North Korea’s facilities’ designs, radiation shielding systems, cranes, protective devices, waste disposal sites and safety control systems are “seriously defective.”

In support of this statement, North Korean defector, Kim Chol-ho (assumed name), attests that during his service with North Korea’s People’s Army, he personally witnessed evidence of leakage of radioactive material at Yongbyon. Dr. Sin Song-kim of South Korea’s Defense Research Institute confirms Kim’s statement. Kim says that he heard from workers at Yongbyon that a nuclear detonation device had been manufactured, but that nuclear warhead production had not been completed.

At the IAEA Board of Governors meeting, member states discuss North Korea’s nuclear situation. The Board agrees that all nuclear-related facilities must be reported at least 180 days prior to construction. Previous regulations required 60 days prior notice.

Roland Prinz, Washington Times, 16 June 1992, p.A7; Yonhap (Seoul), 10 July 1992.

15 June 1992

According to IAEA spokesman David Kyd, the North Korean technology that the IAEA saw at Yongbyon was “30 years old.” Therefore, the IAEA disagrees with CIA reports that North Korea will be able to produce a nuclear weapon in the very near future. However, before making an accurate assessment, the IAEA must conduct additional inspections.

18 June 1992

During the IAEA Board of Governors meeting, O Chang-rim, head of the North Korean delegation, advocates continued bilateral negotiations between the North and South as stipulated by the JNCC. According to O, the major obstacle to the North-South talks is South Korea’s refusal to allow North Korean inspections of US military bases in the South. North Korea fears that these bases may house nuclear weapons. O also says that North Korea will continue to cooperate with the IAEA on inspections, but that construction of the Yongbyon radiochemical laboratory will continue despite international concern.

North Korea says that it intends to continue its present course of nuclear development, including research on a fast-breeder reactor, composite nuclear fuel, and completion of the reprocessing facility at Yongbyon. It insists that its “radiochemical laboratory” (reprocessing facility) will be used to produce fuel for a fast-breeder reactor. The IAEA considers the laboratory a “cause of grave threats to stability and peace” in the region. North Korea says that it must develop an indigenous fuel cycle because it cannot afford to import materials.

South Korean officials believe that North Korea is concealing key elements of its nuclear program. South Korean spokesman on inter-Korean reconciliation Lee Dong-bok says that US and South Korean intelligence observed “vehicle movements in and out of the reprocessing facility” at Yongbyon prior to inspections. US Assistant Secretary of Defense James Lilley says North Korea may “have been moving stuff out of Yongbyon into other areas.”

It is suspected that there is a secret nuclear site in the Yang Gang Do region near the Chinese border. Furthermore, according to former North Korean embassy official Ko Yong-hwan, there is a secret underground research site at Bakchon. Ko also says that North Korea tried to smuggle uranium into the country in the early 1980s.

Warren Strobel, Washington Times, 21 June 1992, pp.A1, A16.

22 June 1992

It is alleged that North Korea has separated plutonium using Soviet equipment. This, however, was not included in the “initial report” given to the IAEA in May 1992. In separating the plutonium, North Korea used hot cells supplied to it in the 1960s, as well as acquired information on reprocessing and laboratories in the 1960s and 1970s. The Soviet Union supplied the hot cells to North Korea under the same agreement that allowed for the sale of the 2MW IRT-research reactor.

31 August-15 September 1992

In preparation for the IAEA’s third inspection visit, North Korea hurriedly installs transmission lines and other related equipment at the 5MW reactor facility at Yongbyon.

The third IAEA inspection team arrives in North Korea on 31 August 1992. The inspections will last two weeks. IAEA spokesman David Kyd says that the IAEA’s inspections will focus on North Korea’s plutonium reprocessing program.

During the inspection, the team is given limited access to two suspected nuclear-related sites at Yongbyon. North Korea had not declared the sites in the report submitted to the IAEA in May 1992. One of the sites is a two-story building that has been partly covered by large mounds of earth and landscaping prior to the inspectors arrival so as to appear as a one-story building. However, US overhead photography recorded the construction of the building prior to the inspection, which shows that the first-story of the building (which is covered up) contains thick-walled vaults made of reinforced concrete. Such construction is suitable for nuclear waste storage. When the IAEA inspection team requests access to this portion of the building, the North Koreans inform them that it does not exist. They are permitted limited access to the second-story of the building, which is found to house heavy weapons, including tanks and missiles on mobile carriages. The North Koreans refuse to allow a formal and thorough inspection of the building based on grounds that it is a military site and thus exempt from inspection. The IAEA, however, does not accept such exemptions.

During the inspection, the North Korean government denies some IAEA inspectors access to its facilities at Yongbyon. It also blocks direct communication between IAEA headquarters and its representatives in North Korea. The team is expected to return on 19 September to brief IAEA Director General Hans Blix.

During the fourth inspection, IAEA Director General Hans Blix telephones chief inspector Willi Theis (at the Yongbyon nuclear complex). According to Blix, the IAEA possess indisputable evidence that a trench had been dug and later covered up between the reprocessing plant and the “one story building” whose basement is believed to be a nuclear waste storage facility. (The structures mentioned are located at the Yongbyon nuclear complex.) He also informs Theis that there is clear evidence that North Korea had attempted to camouflage a nearby outdoor nuclear waste facility. He instructs Theis to inform the North Koreans that they must declare these sites as nuclear facilities and permit inspections. Theis immediately summons two senior nuclear officials at the Yongbyon facility and attempts to work with them on amending North Korea’s initial declaration to the IAEA. They cooperate with the intention of including the waste sites in the report with as little admission of error as possible.

During a summit meeting in Seoul, South Korean President Roh Tae-woo and Russian President Boris Yeltsin agree that North Korea’s nuclear weapons program is “not desirable for peace and security.” They promise to work together to encourage North Korea to “adopt openness and reform.” According to Yeltsin, Russia has stopped supplying nuclear technology and materials to North Korea.

27 November 1992

During the eleventh JNCC meeting, inter-Korean dialogue collapses. North Korea repeats its demand for the cancellation of Team Spirit military exercises. South Korea responds by demanding that North Korea allow a minimum of one inspection before it halts the exercises. South Korea says that the exercises will resume unless substantial progress is made with at least one mutual inspection before the next Prime Ministers meeting in Seoul on 21 December 1992. North Korea uses the Team Spirit military exercise as justification for suspending further joint committee dialogue with South Korea, excluding JNCC meetings.

North Korean Minister of the Atomic Energy Agency Choe Hak-kun, Roving Ambassador O Chang-rim, and other North Korean officials meet with IAEA Director General Hans Blix to discuss North Korea’s implementation of the nuclear agreement. Blix is believed to have notified North Korea that it has not declared all of its nuclear facilities and asks it to “sincerely implement the nuclear agreement.” It is also suspected that North Korea has hidden nuclear facilities because it refused to allow an IAEA special inspection team to enter the country right after it finished its fourth inspection.

IAEA Director General Hans Blix presents the fourth inspection report to the Board of Governors. The report suggests that several nuclear sites in North Korea were not originally disclosed. The IAEA will send a fifth team, as well as a high-ranking official to North Korea to inspect the unreported bases.

According to the South Korean envoy to Vienna, Yi Si-yong, Choe’s willingness to speak with Blix about the inspections is a positive sign.
