37 countries have also signed a UNHRC letter in support of China's Xinjiang policies, the majority of whom are Muslim countries, and these countries include traditional US allies such as Qatar, Saudi Arabia, United Arab Emirates and Kuwait.

FWIW, the number of countries in support of Xinjiang have increased to 46 at the time of this comment.

I don't know how to tell you this, but a lot of Muslim groups don't like other types of Muslims, and China pumps so much money into those states that they likely wouldn't bat any eye anyhow, especially with Qatar and Saudi Arabia having their own slavery problems.

Explain to me why Sunni Muslim (same as Uighur) countries like Saudi Arabia, Yemen, Qatar, and the UAE signed the letter in support of China, all of whom obtain more funding, arms, and security from the US than China?

Because (oversimplifying, but still) on one side Pakistan, and on the other Israel.

Can you elaborate? You essentially just hand waved over my points and said "because Pakistan, Israel."
