This annotated chronology is based on the data sources that follow each entry. Public sources often provide conflicting information on classified military programs. In some cases we are unable to resolve these discrepancies, in others we have deliberately refrained from doing so to highlight the potential influence of false or misleading information as it appeared over time. In many cases, we are unable to independently verify claims. Hence in reviewing this chronology, readers should take into account the credibility of the sources employed here.
Inclusion in this chronology does not necessarily indicate that a particular development is of direct or indirect proliferation significance. Some entries provide international or domestic context for technological development and national policymaking. Moreover, some entries may refer to developments with positive consequences for nonproliferation.
Iran purchases 20 Scud-B missiles from North Korea.
—Steven Emerson, "The Postwar Scud Boom," Wall Street Journal, 10 July 1991, p. A12.
North Korea's first test of its modified Scud-C is believed to have been a failure. [Note: This conflicts with the first report of a North Korean Scud-C flight test in May 1986.]

The North Korean Navy completes construction of a surface-to-ship missile base at Mt. Kanggamch'an, across from the Kanepo Fisheries Cooperatives in Chungsan-kun, South Pyŏngan Province. This facility also has an intermediate-range missile base that was completed around 1985.
—Testimony of Ko Yŏng Hwan, former North Korean Foreign Ministry official, before the US Senate, 21 October 1997.
According to Ko Yŏng Hwan's testimony before the US Senate, the North Korean Military Construction Bureau begins construction of a missile base in "Chungganjin, Huch'ang-kun, Chagang Province." According to Im Yŏng Sŏn, North Korea plans to finish the construction by 1995. [Note: Ko's reference is incorrect. There is no "Chungganjin, Huch'ang-kun" in Chagang Province. There is a "Hŭich'ŏn City," but it is at the southern end of the province, and this conflicts with other reports of the missile base's location. The base is probably located at Chunggang-kun, Chagang Province, near the Chinese border. There are references to both "Chinggang" and "Chungangjin" in South Korean press reports.]

South Korean President Roh Tae Woo meets with Soviet President Mikhail Gorbachov in San Francisco, where they agree in principle to establish diplomatic relations, and "to expand economic, scientific, and technical links." The meeting infuriates the North Korean leadership, and seriously worsens already deteriorating North Korea-USSR bilateral relations. North Korean media later criticized Roh for his "flunkeyist, submissive and traitorous trip," and also say, "Our people cannot but have a doubt about the attitude of the Kremlin which sat face-to-face with such a dictator."
