The U.S. needs to do much more of this:
The Chinese understand their own government quite well. That is why wealthy Chinese move their money out of China and buy real estate in Canada and the United States. Cities along the West Coast and a few others (e.g. Toronto) have had a major influx of Chinese buying expensive (multi-million-dollar) homes, usually paying cash for them.
So, restricting visas may have some impact to those wealthy (and influential) Chinese, and at the very least, sends a message that the U.S. is paying attention to what is happening in Xinjiang.
The Trump administration has also discussed limits/regulations on U.S. capital being invested in Chinese markets and companies. We think such limits and regulations should also be put in place. China’s economic rise was largely financed by capital from western countries, Japan, and Taiwan investing in China after the “opening up.” That rise was unequivocally good for the Chinese people. But there is no good reason for U.S. capital to continue to fund oppression by the CCP under Xi Jinping’s increasingly totalitarian, nationalistic, and closed rule.
