What did the declassified documents reveal?

This episode presents a declassified Central Intelligence Agency assessment of Sino‑Soviet relations, dated January twenty‑third, nineteen‑seventy‑nine. The document is notable because it reveals how U.S. analysts viewed the interplay of Chinese, Soviet, and Vietnamese actions at a pivotal moment in the Cold War. The source is available through the public archive at archive.org. The record was released for public inspection on December sixteenth, two thousand four, under the authority of the Central Intelligence Agency’s declassification board. It appears in the CIA’s Electronic Reading Room with the reference CIA‑RDP83B00100R000100030030‑0. The Black Vault hosts a transcription of the original text. Now, the document itself. Twenty‑five N‑S‑A reviews completed. Four, twenty‑third January, nineteen‑seventy‑nine, D‑C‑I congressional briefing. Sino‑Soviet I. Polarization and tension. A. Already mentioned Japanese and U‑S moves toward the People’s Republic of China. B. Vietnam‑Kampuchea mainly responsible for current rise in tension. 1. Issue is will the People’s Republic of China retaliate? a. Some Chinese say “teach Vietnam a lesson” – no “paper tiger.” b. But political objections – impact on Sino‑U‑S, Soviet reaction. 2. Meanwhile, forces mounting – major elements near the North Vietnam border map of two armies, combat support elements of two others. Half of MIG‑21 force now in area. 3. Now in position for offensive thrust. 4. Soviets dominate military balance on the Sino‑Soviet border. 5. Must worry about PRC strategic forces. It is to the Sino‑Soviet relationship that I would now turn because much of what each nation does in the outside world can be explained in terms of the rivalry and tense relations between them. II. Beijing’s current anti‑Soviet strategy is keyed to the strengthening of political and economic relationships with the West—particularly with the United States—and with Japan. They have reason to be satisfied with developments in the past year. A. Both the United States and Japan agreed to language the Soviets consider anti‑Soviet in joint documents issued in connection with the normalization of Sino‑U‑S diplomatic relations last month and the conclusion of the Sino‑Japanese Peace and Friendship Treaty last October. B. Chairman Hua Guofeng’s visits to Yugoslavia and Romania last fall demonstrated Beijing’s willingness and capability to take on the Soviets in their own backyard. The Chinese have significantly improved their trade ties with Western Europe and Japan, and are on the verge of their first modest arms purchases abroad. These developments strengthen Beijing’s image as a normal, stable country, and demonstrate China’s determination to deal effectively with the Soviets on
