What did the declassified documents reveal?

Developments in Sino‑Soviet Relations – an intelligence memorandum from the Central Intelligence Agency dated July sixteenth, nineteen seventy‑three. The document is notable because it records how both Beijing and Moscow responded to the Brezhnev‑Nixon summit and to a parallel Chinese diplomatic tour, offering a snapshot of Cold War maneuvering in Europe and Asia. The memorandum was released through a Freedom of Information Act request. The declassification authority noted the material as “Top Secret” but approved for public release on August fourth, two thousand four. The record is now available in the public domain via The Black Vault and the Internet Archive. The memorandum opens with an assessment that, since the announcement of the Brezhnev‑Nixon summit in early May, the rivalry between the People’s Republic of China and the Soviet Union has focused on competition for Washington’s favor, a factor that has long shaped the policies of both Beijing and Moscow. Within days of the summit dates being announced, Beijing, worried that the summit would advance détente in Europe, completed plans for a diplomatic tour of its own. Foreign Minister Chi Peng‑fei was sent to Europe, where he reiterated China’s pro‑U.S., pro‑NATO, and anti‑Soviet positions. Moscow, sensitive to Chinese “meddling” in Europe, seized every opportunity to disparage Chi’s trip. The Soviets presented the summit as an event of extraordinary significance, but let the agreements speak for themselves and did not imply that they were aimed at any third party. Beijing gave the event almost no media coverage. In private, the Chinese dismissed the agreements as “meaningless,” but were probably concerned that the overall impact of the summit would relax U.S. and Western vigilance and make it more difficult for China to play upon European fears of Soviet expansionism. The memorandum notes that while the Washington‑Moscow‑Beijing triangle captured most attention, both Beijing and Moscow continued to jockey for position in Japan and North Korea. Improvement in Soviet‑Japanese relations slowed to a crawl, and Premier Kim Il‑song expressed discontent with both of his powerful allies. A diplomatic tour was organized twelve days after the summit dates were announced. The Chinese foreign minister traveled to London, Paris, Tehran, and Karachi. The itinerary itself conveyed a message. By stopping first in London, Chi signaled that Beijing now found Britain’s pro‑U.S., pro‑NATO, and pro‑European posture more congenial than the more “independent” policies of France, China’s oldest friend in Europe. A stop‑over in Tehran suggested a new interest in Persian Gulf politics with a declining concern over purely Arab matters. During his visits, Chi emphasized repeatedly that Europeans must place renewed emphasis on their defense ties with Washington and be wary of Soviet efforts to “dislodge” the United States from Europe. He warned that of the two superpowers, the United States was on the defensive, and…
