Of the 1 million foreign nationals enrolled at U.S. schools, nearly one-third are from China -- double the number of any other country. Chinese students receive 10 percent of all doctorates awarded in the U.S., most of them in science and engineering. Some 80 percent of Chinese doctoral holders stay in the U.S. and work after they earn their degrees. There are more Chinese engineers working on artificial intelligence at U.S. technology companies than in all of China.
IMHO it's better for us to export our intellectual property to China while importing and keeping their best brains.
