What did the declassified documents reveal?

Declassified. Today's briefing examines a declassified Central Intelligence Agency record, "United States Policy Concerning Chinese Off-Shore Islands Held by the National Government of China, 1950-1952." This document, published by vault.fbi.gov, provides historical context on U.S. involvement in the Taiwan Strait. This four-page memorandum, dated December twenty-first, nineteen-sixty-one, was part of a larger collection of U.S. intelligence on China and was released under a Freedom of Information Act request. It offers an internal C-I-A perspective on U.S. policy shifts regarding Taiwan and surrounding islands.

"The first serious incident bearing on this United States position occurred when a Taipei newspaper reported that the Chinese Air Force had bombed more than one hundred and fifty Communist ships in the area of Quemoy Island, so as to frustrate an invasion attempt against that island. The Department, through Embassy Taipei, requested full information from the Chinese Foreign Office, which explained that the reason for the bombing was the concentration of Communist shipping in preparation for an invasion of Quemoy, after an earlier Communist landing attempt on a smaller nearby island had been repulsed. The Department considered the explanation unsatisfactory and the bombings to be outside the scope of 'defensive action', but it lodged no protest." "The new situation regarding Taiwan led to renewed military assistance to the Chinese National Government, following study of the possible political implications, but there appears to have been, in this connection, little, if any, political discussion with respect to the offshore islands. General MacArthur told W. Averell Harriman, special representative of the President, in a conversation in Tokyo on August twentieth, nineteen-fifty, that he had…
