China has called on the United States to halt efforts to broaden restrictions on American investment in key Chinese technology sectors. The appeal comes in response to a recent proposal by the U.S. Treasury Department aimed at extending existing controls to include biotechnology, advanced computing, and hypersonic technology.

The expanded restrictions seek to limit outbound U.S. investments in areas deemed critical to national security, as part of a broader strategy to curb China’s technological advancement. Officials in Beijing described the move as discriminatory and warned it could harm bilateral economic relations.

Chinese authorities argue that the new measures contravene prior commitments made between the two countries' leadership and risk undermining cooperation on trade and investment. They emphasized the importance of maintaining open channels for technology and capital flow to support shared economic growth.

The U.S. administration maintains that the expanded curbs are necessary to protect sensitive technologies from potential misuse or diversion. Treasury officials contend that restricting investments in emerging strategic sectors helps safeguard national security interests in an environment of increasing geopolitical competition.

As discussions continue, the dispute highlights ongoing tensions between Washington and Beijing over technology development, trade policies, and efforts to balance economic engagement with security concerns. Both sides have indicated a willingness to engage in dialogue, but significant differences remain regarding the scope and justification of investment controls.
