DETER Act of 2023

The DETER Act of 2023 requires the President to annually certify whether China’s military or economic actions violated Taiwan’s sovereignty. If certification fails (e.g., due to military aggression or economic coercion against Taiwan), the U.S. would suspend normal trade relations with China, triggering higher tariffs on all Chinese imports. The bill also mandates a supply chain assessment identifying U.S. dependencies on Chinese goods and proposals to diversify sourcing. These provisions directly affect U.S.-China trade policy, tariff rates, and supply chain strategies for critical goods.
