Hello! I'd be happy to help you with that question.
The action that made China reluctant to improve relations with the United States was A. Chinese-Soviet border disputes. During the Cold War era, China had significant border disputes with the Soviet Union, leading to tensions between the two countries. The United States, being an adversary of the Soviet Union, tried to improve relations with China as a way to counter Soviet influence. However, China's focus on resolving its conflicts with the Soviet Union made it reluctant to fully engage with the United States.
These border disputes were a crucial factor in shaping China's foreign policy at the time, and they influenced China's approach to international relations, including its interactions with the United States. By prioritizing its disputes with the Soviet Union, China was less inclined to align itself closely with the U.S., despite U.S. efforts to improve relations.
I hope this helps clarify why Chinese-Soviet border disputes made China reluctant to improve relations with the United States. If you have any more questions or need further explanation, feel free to ask!
