After the Communists seized power in China in 1949, the US openly viewed Chinese Communism as benign, and thus distinct from Soviet Communism. And it was after the Communists crushed the pro-democracy movement in 1989 that the US helped to turn China into an export juggernaut that has accumulated massive trade surpluses and become the principal source of capital flows to the US.
1949年中共建政后，美国公开对中共示好，并将其与苏共区别对待。1989年中共镇压民主运动后，美国又帮助中国成为世界出口冠军，中国因此积累了巨额贸易盈余，也成为美国资本流入的主要来源。
