Core Viewpoint - The recent export control measures by the U.S. Department of Commerce, particularly the "penetrating rules," will significantly impact thousands of Chinese companies, as subsidiaries with over 50% ownership by entities on the U.S. "Entity List" will face the same export restrictions as their parent companies [1][8]. Group 1: U.S. Trade Measures - The U.S. has implemented multiple unilateral trade restrictions, including "301 investigations," "reciprocal tariffs," "penetrating rules," and "232 tariffs," which have escalated trade tensions with China [3][4]. - The "301 investigation" is seen as a symbol of U.S. unilateralism, allowing the U.S. Trade Representative to investigate and impose sanctions on perceived unfair trade practices by other countries [4][5]. - The "reciprocal tariffs" policy, pushed by the Trump administration, aims to enforce equal tariff rates between the U.S. and its trading partners, which has led to higher tariffs for U.S. goods compared to other countries [5][6]. Group 2: Export Control Measures - The newly implemented "50% penetrating rule" requires subsidiaries of sanctioned entities to comply with the same export licensing requirements as their parent companies, further tightening restrictions on China's technology sector [8][9]. - This rule is expected to force many Chinese companies to reassess their global investment strategies and subsidiary structures, potentially leading to adjustments in ownership ratios and supply chain management [8][9]. - The U.S. has also expanded its "Entity List," which prohibits listed companies from engaging in any commercial transactions with U.S. entities, representing a direct attempt to suppress foreign competition [11][12]. Group 3: Impact on Global Trade - The unilateral measures by the U.S. are viewed as detrimental to international trade norms and have been criticized for undermining the stability of global supply chains [1][11]. - The World Trade Organization (WTO) has previously ruled that certain U.S. tariffs, such as those under the "232" measures, violate international trade rules, highlighting the contentious nature of U.S. trade policies [9][10].
