Senior US lawmakers have urged the Biden administration to enhance export controls on semiconductor manufacturing equipment to prevent China from accessing advanced chipmaking tools that could enhance its military and artificial intelligence capabilities. In a bipartisan letter to Secretary of State Marco Rubio and Commerce Secretary Howard Lutnick, House Select Committee on China Chairman John Moolenaar and House Foreign Affairs Committee Chairman Brian Mast emphasized the need for robust export controls and closer coordination with allies. The lawmakers highlighted that semiconductor manufacturing equipment controls are crucial in the strategic competition with China, as these tools are vital for producing advanced AI chips and legacy chips used in military systems.
The letter, also signed by other key lawmakers, stressed the importance of maintaining restrictions on semiconductor manufacturing equipment for US national security. While acknowledging progress made in export controls, the lawmakers cautioned about existing critical gaps in the export control regime, particularly concerning certain foreign-produced chokepoint equipment controlled only for specified Chinese entities. They emphasized that entity-specific controls are insufficient substitutes for countrywide restrictions on essential chokepoint tools, as once the equipment enters China, enforcing end-use and end-user restrictions becomes extremely challenging.
US lawmakers referenced a recent bipartisan report and a House hearing highlighting China’s accelerated imports of foreign-produced chokepoint equipment in recent years. They expressed concerns over Dutch sales of advanced lithography equipment to China doubling in recent years and reports suggesting China may be upgrading imported tools to surpass export control thresholds. The lawmakers urged the administration to work with allies to implement countrywide controls on key semiconductor equipment and subcomponents, including those that China cannot produce domestically, and emphasized the need for clear deadlines for action.
The debate over chip export controls has intensified as the US considers semiconductor technology crucial for economic competitiveness and national security. While the US has tightened restrictions on advanced chips and manufacturing tools to limit China’s advancements in AI and military technologies, differences remain with key players like the Netherlands and Japan over the scope and enforcement of controls, especially as China aims for greater self-sufficiency in chipmaking.
