What problem made china reluctant to improve relations with the united states? apex answer

American support for Taiwan.

Explanation:

The relations between Taiwan and the United States have not always been clear. Before the Chinese civil war, these relations were conducted directly with China. However, after 1979, when the United States normalized diplomatic relations with China, independent relations with Taiwan were carried out in an unofficial and informal way. Since 2018, relations between the U. S. and Taiwan have become official. This has made China reluctant to improve relations with the United States, as China does not consider Taiwan independent.
