Cable from the Chinese Embassy in Pakistan describes different responses of Pakistani government officials and foreign government diplomats in Pakistan regarding China's first nuclear weapons test.

Intelligence reports about recent visits to Beijing by Pakistani defense and science officials raised questions whether China was or would be providing nuclear aid to Pakistan. The latter was already developing close relations with China, a matter which was of great concern to U.S. policymakers, but INR analyst Thomas Thornton concluded that Pakistan was highly unlikely to seek a significant degree of Chinese nuclear assistance.

With nuclear proliferation a policy priority for the Jimmy Carter administration, and Pakistan already a special concern, the possibility that China and Pakistan were sharing nuclear weapons-related information began was beginning to worry US government officials. They had no hard evidence--and the soft evidence that concerned them is massively excised in the December 1979 report just as Beijing and Washington were normalizing relations—so the “precise nature and extent of this cooperation is uncertain.”

Despite the concerns about sharing the ALR-69 radar warning receiver with Pakistan for fear of it falling into Chinese hands, CIA officials argue that failure to meet Pakistani demands would lead to a “serious blow to U.S. worldwide nonproliferation efforts.”

With delivery of U.S. F-16 fighter-bombers imminent, Pakistan threatens to refuse delivery unless the U.S. agrees to include the ALR-69 radar warning receiver for the aircraft. CIA analysts have concerns that including this sensitive radar technology in the delivery of the F-16s would enable China, a close military ally of Pakistan, to obtain and study the device.

The U.S. Embassy in Pakistan reports to the State Department on a meeting between Ambassador General Vernon Walters and President Zia. Walters returned to Islamabad to warn Pakistani officials that U.S. aid was in “grave jeopardy” after a link between the Pakistani program and Chinese technology was discovered. A U.S. military aid package, which included F-16 fighter-bombers, was also discussed.

A summary of U.S. State Department cable traffic regarding Pakistan’s nuclear efforts in 1981-1982. While the Reagan administration was inclined to give Pakistan some leeway in light of their support for anti-Soviet forces in Afghanistan, the acquisition of sensitive nuclear technology from abroad was still something that the administration was against. Evidence that Pakistan had made efforts, some successful, to acquire specific technology that suggested a nuclear test was being prepared raised a red flag in the U.S. government
