In the late 1960s and early 1970s, the Sino-Soviet conflict intensified and at the same time the Sino-American rapprochement was well under way. When the Americans began to search for an answer to the question of ‘Why Vietnam’, some US foreign relation documents in the later 1940s were released, which indicated that the Chinese Communist Party (CCP) had made certain friendly overtures toward the United States. Since then, it has become a widely-accepted interpretation among scholars that Washington ‘lost a chance’ to win over the CCP from Moscow in the late 1940s. The fundamental premise of this interpretation is that the CCP earnestly bid for American friendship and support as a counterweight to pressure from the Soviet Union. It is argued that the CCP sincerely sought the US recognition right up to the middle of and that it was only after their bids for American support were rejected by Washington that the Communists had to choose the ‘lean-to-one-side’ policy. In short, Washington's shortsighted policy in 1949 ‘forced Beijing into Moscow's embrace’, and therefore set in motion a train of disastrous events: the Korean War and the Vietnam War. A promising postwar Asian balance in favour of the US was ruined.
