Ambassador for Disarmament Affairs and Deputy Permanent Representative of the People’s Republic of China to the United Nations Office at Geneva.

With a nuclear nonproliferation treaty under consideration in Washington, INR considered which countries were likely to sign on and why or why not. INR analysts, mistakenly as it turned out, believed it unlikely that the Soviet Union would be a co-sponsor of a treaty in part because of the “international climate” and also because Moscow and Washington differed on whether a treaty would recognize a “group capability.”

This lengthy report was State Department Bureau of Intelligence and Research's contribution to the first National Intelligence Estimate on the nuclear proliferation, NIE 100-6-57.

Memo from Foreign Minister Saraiva Guerreiro to President João Batista Figueiredo on the current state of, and potential for the future of nuclear cooperation with China, in the follow-up to the presidential visit to Beijing. Guerreiro recalls that, since China was also not a party to the NPT, nuclear cooperation and purchase of material, like the uranium acquired in 1982, would not be subjected to full-scope safeguards, preserving the “sovereignty of Brazil’s nuclear program.” Guerreiro mentions a study by the National Security Council, the Nuclear Commission, Nuclebrás and the Foreign Ministry on the commercial and technological potential for an agreement with China, similar to the ones that Brazil had already signed with “other developing countries, namely those that are not members of the NPT.” One such agreement, Guerreiro suggests, could be signed during President Figueiredo’s upcoming visit to Beijing.

The Bulgarian Embassy in Havana reports to the Central Committee of the Bulgarian Communist Party and the Bulgarian Ministry of Foreign Affairs on political, economic, and cultural developments in Cuba circa 1963. Cuba is politically united, but is experiencing economic hardship after the “Caribbean Crisis” primarily because of the US embargo. In the report, embassy staff reviews developments between socialist countries and Cuba throughout 1963. Some examples include communist aid to Cuba after Hurricane Flora and Cuba’s stance on Sino-Soviet relations. Bulgaria’s show of solidarity resulted in concrete political, economic, and cultural cooperation. Embassy staff notes the drawbacks and benefits of Bulgaria’s relationship with Cuba.

The State Department writes to Islamabad urging Pakistan to not react if in fact India chooses to launch a nuclear test. On 15 December the New York Times published a story by Tim Weiner, under the headline “US Suspects India Prepares to Conduct Nuclear Test.” While some Indian journalists and policy experts were convinced that the story was a US government plant, Weiner had simply used due diligence in pursuing a lead from a non-government expert on nuclear proliferation issues. Worried that the story would exacerbate regional tensions by encouraging Pakistan to “act in a manner that jeopardizes our nonproliferation efforts in South Asia,” the Department wanted to enlist the Chinese to encourage the Pakistanis to “exercise restraint in response to these reports.”
