Which treaty did the United States sign with the Republic of China in December 1954 to defend the Taiwan Strait?

• A. ANZUS Treaty
• B. Camp David Accords
• C. Strategic Arms Limitation Treaty
• D. Sino-American Mutual Defense Treaty

Answer: (D)

The main idea here is identifying the security pact the United States signed with the Republic of China to defend Taiwan. That agreement is the Sino-American Mutual Defense Treaty, signed in December 1954, which established a mutual defense obligation between the United States and the ROC in the Taiwan Strait. It was meant to deter Communist aggression and ensure U.S. support for Taiwan in the face of potential conflict. The other options involve different partners and purposes: ANZUS is a defense pact with Australia and New Zealand; Camp David Accords are peace agreements between Israel and Egypt; the Strategic Arms Limitation Treaty is an arms-control agreement with the Soviet Union.
