Chinese media reported that four Chinese science and engineering students were investigated by US law enforcement officers, and the research direction of two students was related to artificial intelligence (AI).

China Daily Saturday (June 22) quoted sources reported that the four Chinese students who went to study in the United States and participated in academic conferences were repatriated by the United States for no reason.Law enforcement officers of the U.S. Customs and Border Protection brought the four to the "Little Black House" for more than ten hours to conduct more than ten hours of searcation, and conducted many induction and coercion questions.Repeated questions from the Communist Party of China and whether they cooperate with the Chinese government, etc., especially focus on political backgrounds such as party members and computer -related scientific research backgrounds.

It is reported that the United States forcibly detains one of the electronic products and repatriated the other three in the absence of factual basis and effective permission.The United States also rejected two parties to contact family friends, causing one of them to lose contact with the outside world for more than 30 hours.

Reporting incomplete statistics said that in recent years, the United States has been repatriated for no more than 30 repatriands in recent years.Most of the Chinese students related to computer -related majors are masterpieces, including more than half of the doctoral students. Most of them come from well -known universities in the United States. The research direction covers artificial intelligence, information science, network security, electrical, software engineering, electronic information engineering and other fields.

The report also quoted sources as saying that the United States' approach far exceeds the scope of normal law enforcement and has strong ideological prejudice. The purpose is not to maintain the security of the national border, but to prevent the development of Chinese science and technology and maintain American science and technology hegemony.

Chinese officials have criticized the United States for a while for a period of time this year.There are nearly 300 Chinese citizens who have been repatriated by the United States for no reason.
