Answer:
The Taiwan issue, Korean and Vietnam wars.
Explanation:
China And United States has experienced ups and downs in regards to thier diplomatic relations. They were okay during World War II, but things started to change at Cold War. Here you can see some events that strained China-USA relations:
- During Korean War, United States and China supported South and North Korea respectively.
- During Vietnam War, the situation repeated like in Korea: North Vietnam was supported by China while South Vietnam was supported by United States.
- The Taiwan issue. United States supported the Chinese faction in Taiwan and only recognized Taiwan as the only offcial republic of China for many years.
Nowadays, China and United States represents two different economical and political visions about how to govern a country. They have opposite views on many aspects resulting from the ideologies each nation promoted during the Cold War events and later years. That is why China and United States are reluctant to have a better relation like before.
