America Has Lost Its Leverage Over China

The United States and China recently reached a significant agreement that has reshaped the dynamics of their trade and national security relationship. As part of the deal, the U.S. withdrew a new regulation aimed at closing loopholes in export controls on advanced semiconductor sales to China, effectively allowing Beijing to influence how Washington enforces its national security measures related to export restrictions. Additionally, the U.S. agreed not to impose new export controls targeting Chinese entities, marking a notable shift in American policy during ongoing tensions between the two powers. This development follows a period of escalating trade conflict and export control measures initiated under both the Trump and Biden administrations. These controls were originally designed to prevent China from leveraging U.S. technology for military purposes, supporting Russia’s war in Ukraine, and committing human rights abuses in Xinjiang. However, the recent agreement, known as the Busan deal, grants China a degree of authority over U.S. enforcement actions that was previously unimaginable, effectively giving Beijing a "vote" on American national security decisions. While some view the agreement as a diplomatic breakthrough that prevented further economic escalation akin to Cold War arms control negotiations, the deal is notably asymmetric. China relinquished its strictest restrictions on rare earth exports, a critical resource for U.S. industries, in exchange for the U.S. halting export controls across multiple sectors including technology, cybersecurity, and nonproliferation. This imbalance has strengthened China’s position in the bilateral relationship, complicating efforts by current and future U.S. policymakers to restore a more favorable and stable framework for managing competition and cooperation with Beijing. The agreement underscores the strategic importance of rare earth elements and highlights the challenges the U.S. faces in maintaining leverage over China amid deep economic interdependencies. It also signals a shift in how national security concerns are negotiated between the two countries, with potential long-term implications for global technology supply chains, geopolitical stability, and the balance of power in international trade.
