川普讲话是大嘴巴，不值得太多关注

但他上台后，对美华的伤害是实打实的。。

斯坦福大学刚刚出炉了一个关于川普当初搞China Initiative的研究报告

• China has been the most important foreign supplier of U.S.-based scientists for more than two decades
• The number leaving has steadily increased. After the Department of Justice implemented the "China Initiative" in 2018, departures increased by 75%, with two-thirds of the relocated scientists moving to China.
• Surveyed scientists of Chinese descent in the U.S. report anxiety and new difficulties in pursuing their research, with 61% considering leaving the U.S. and 45% avoiding federal grant applications
• According to the online survey, 35% of Chinese scientists in the U.S. felt unwelcome; 72% did not feel safe as academic researchers; 42% were fearful of conducting research; 65% worried about collaborations with China; and 86% perceived it was harder to recruit top international students compared to five years ago. Additionally, 83% had experienced insults in a nonprofessional setting in the previous year.
• Of the five possible reasons for “not feeling safe as an academic researcher in the U.S.,” most survey respondents pointed to fears of “U.S. government investigations into Chinese-origin researchers” (67%) and “Anti-Asian hate and violence in the U.S.” (65%).
