1. China does not share liberal values. They have been genociding Uighurs for many years.

2. China is bent on expanding territory. It has border disputes with nearly all of its neighbors. https://asianews.press/2020/06/30/china-has-border-dispute-l...

3. China has threatened military action against western allies, like Taiwan.

4. China has repeatedly violated promises that its made, like the Hong Kong handover.

5. China steals sensitive technology and manufacturing plans from foreign companies. It has mandated that foreign companies establish joint ventures with Chinese companies to do business in China, with unrestricted access to all internal company documents and systems of the foreign company.
