China has lodged solemn representations to the United States regarding the recent wanton repatriation of a Chinese student with a legal visa by the U.S., the Chinese Embassy in the United States said in a statement on Wednesday. 

The U.S. side wantonly interrogated the Chinese student with a legal visa issued by the U.S. government at the border entrance. After being confined in a small room for more than 50 hours without proper food and rest, he was deported by the U.S. side through a third country on trumped-up grounds, the statement said. 

The U.S. action seriously infringed upon the legitimate rights and interests of the student and caused serious physical and mental damage to him and his family, and China will continue to support Chinese students in safeguarding their legitimate rights and interests in accordance with law, the statement added.
