ABSTRACT
Prior to Vance's visit to China, he has been to Europe, and has also visited Israel and talked with some Middle East countries. However, that journey was not fruitful. At present, on the diplomatic front, the United States is anxious about solving the problems of peace negotiations for the Middle East, arms limitation with Soviet revisionism, the Rhodesian problem together with Britain, and normalization of relations between China and the United States. The United States and Taiwan have signed many agreements and treaties, one of which, the US-Taiwan mutual defense treaty, is one of the obstacles to the solution of China-U.S. relations. It stipulates that if Taiwan should be attacked by some other party, under this treaty, the United States must come to the aid of Taiwan, by sending troops, by supplying arms, and by joint counterattack. The United States is a developed capitalist nation, whose industrial workers are very powerful and constitute a vast reservoir of strength for revolution.
