As barkingcat suggests, pretty much every country on the planet that has normalized diplomatic relations with China formally accepts the One China policy. This is part of China's chess strategy for forcing the world to accept its ownership of Taiwan.

I will go out on a limb for a second and suggest that the day will come soon enough when the United States formally bends the knee on this issue as well. We are headed in that direction much faster than anyone anticipated.

The 'free world' has chosen to worship the Almighty Dollar as its lord and sovereign. China is where most of your dollars come from now. Ergo, China has the mandate of market-capitalist heaven, and you work for China now.
