Which countries signed the Nuclear Test Ban Treaty in 1963?

• A. France and China
• B. United States, Soviet Union, and United Kingdom
• C. United States only
• D. Soviet Union and United Kingdom only

Answer: (C)

Understanding which nations signed the 1963 Nuclear Test Ban Treaty centers on recognizing that this agreement, the Partial Test Ban Treaty, was signed by the United States, the Soviet Union, and the United Kingdom. The treaty prohibited nuclear tests in the atmosphere, in outer space, and underwater, aiming to reduce radioactive fallout and ease Cold War tensions. These three powers were the major nuclear actors driving the negotiations at the time, which is why they are the signatories. France and China were not signatories in 1963, and the option with only the United States omits the other two key participants. So the nations that signed in 1963 are the United States, the Soviet Union, and the United Kingdom.
