History tends to repeat itself. The USA has a long history of racism including Sinophobia. Just listen to how Rubio and other US politicians talk about China and what they perceive as the Chinese threat.

In 1850, Chinese arrivals to San Francisco were welcomed at a public ceremony, but as their numbers grew the sentiment toward them turned ugly.

Politicians, sensing an opportunity, began to call for the removal of Chinese residents.
