What did the declassified documents reveal?

The document we read today is a Central Intelligence Agency analytical piece on the emerging split between the Soviet Union and the People’s Republic of China, written in the early 1960s. It is notable because it captures the internal debate within the United States intelligence community as the once‑assumed Sino‑Soviet alliance began to fracture. This record was released to the public through The Black Vault archive, where it appears as a digitized text file. The file was posted without a formal FOIA case number, and the declassification authority is listed as the Central Intelligence Agency, which cleared the material for public dissemination. The CIA and Double Demonology Calling the Sino‑Soviet Split Harold P. Ford Once it was widely believed that the USSR and Communist China were firm allies acting in concert to spread Communist influence everywhere they could in the world. In the early 1950s, there was much to support that image. Harold P. Ford held senior positions in both the National Intelligence Council and the Directorate of Operations. Sino‑Soviet relations are in a critical phase just short of an acknowledged and definitive split. There is no longer much of a fundamental resolution of differences.

An environment of continued sharp, military bipolarity will leave the two partners little choice but to repress their differences and carry on. [Ambassador Charles (Chip) Bohlen:] I am inclined to agree with George… there is not the slightest sign that any adjustments of the basic elements of that dispute have been or are in process… Comments on NIE 11‑5‑62, May 1962 The Soviet party is opportunist and revisionist; it lacks any deep knowledge of Marxism; its ideas about disarmament are absurd; peaceful coexistence could mean nothing, except as a tactical weapon to deceive the enemy; the Soviet idea of a division of labor among the countries of the socialist camp is wrong; and China must go her own way. Deng Xiaoping, November 1960? Once it was widely believed that the USSR and Communist China were firm allies acting in concert to spread Communist influence everywhere they could in the world. In the early 1950s, there was much to support that image. Mao Tse‑tung’s regime had triumphed in China and then allied itself formally with the Soviet Union. Communist North Korea had invaded the Republic of Korea. Communist China had intervened massively in that war. The USSR had provided its Communist allies with military assistance, including Soviet‑piloted MiGs. The trouble was, among US policymakers such an image of Sino‑Soviet solidarity persisted long after the Moscow—Beijing relationship had in fact begun to fray, badly. Furthermore, that image persisted long after officers from…
