With the help of recently declassified documents, this article examines the link between triangular diplomacy and the Vietnam War. It argues that from the summer of 1971 to the conclusion of the Paris Agreements in January 1973 Kissinger tried to 'sell' a peace agreement to his Soviet and Chinese interlocutors by stressing the American willingness to accept a 'decent interval' solution: that is, the United States would not reenter the war provided that the collapse of the South Vietnamese government did not occur immediately after the last US ground troops returned home. While such a posture played a significant role in increasing Sino-Soviet pressure towards a negotiated settlement, Kissinger's policy also served to bolster the subsequent competition between Moscow and Beijing over influence in Indochina.
