According to CNBC's "China Watch" newsletter, China officially began restricting citizens who violate technology export controls from leaving the country on Tuesday, aiming to plug loopholes in technology and capital outflows. In addition, the U.S. Department of Homeland Security announced that, effective September 15, the grace period for student visa holders before departing the U.S. will be shortened, and the visa duration for journalists from mainland China will be reduced to 90 days, in response to technology transfer risks. These measures reflect the intensifying competition between China and the United States in the technology sector, with both sides strengthening scrutiny over the flow of technology and talent.
