Do you remember the history of Taiwan?
The Empiror's son went to school in Hawaii and became a Christian and capitalist.
He went home and began to spread these things and promoted them.
At the same time Communism was on the rise. And the Empiror's son and his followers were exiled to the island of Taiwan.
Over the decades Taiwan has become very wealthy and now can purchase mainland China. The Communist regime in China wants them back and refuses to let them be an independent nation. They want their money and control over the people. Even if it means using military force to do so.
And that's the rift...pure and simple. China doesn't want to go backwards because of their Communism, they want to gain more control and resources. Their bank is actually in need of a cash infusion because of their manipulation of their yen.
It's not going to work out for anyone if China tries to grab Taiwan, or if they fail economically as a government... like Russia has, EU is on the brink of, or anyone else in financial trouble over this Corona Virus.
