中美共同防禦條約
The Sino-American Mutual Defense Treaty with the Republic of China was signed in December 1954. He requested and secured from Congress their "Free China Resolution" in January 1955, which gave Eisenhower unprecedented power in advance to use military force at any level of his choosing in defense of Free China and the Pescadores. The Resolution bolstered the morale of the Chinese nationalists, and signaled to Beijing that the U.S. was committed to holding the line.
