Taiwan and Tibet are part of China, but has a deal to keep the governments mostly separate until a certain date. China has made some efforts to make the changes gradual. There has been some resistance to the changes, but they are largely exaggerated or directed and paid for by the West. The U.S. official behind the murderous Contras in South America now heads a program that's paid at least $29 million to HK terrorists. Having read the CIA documents that instructed the contras to destabilize and overthrow South American states, I have no doubt there is effectively anti-China Contras/terrorists receiving the same or similar instructions and training. China is using it's power to dramatically improve parts of the world that the US has become dependant on exploiting. The West is very interested in creating a barrier between China and the Pacific to limit it's access to trade with the Americas and elsewhere. Thankfully China has many contingency plans for this and Trump's off-putting style of diplomatic relations may lose the US from friends. A better world could emerge with China's leadership, but HK, Taiwan and elsewhere may suffer attacks on civilians from US-backed thugs, and of course damage to infrastructure designed to hurt their economies. America's track record in this has not been great, and I doubt their strategy against China is fought with even more short-comings.
