Major automakers, suppliers and dealers are urging President Trump to preserve policies barring Chinese companies from selling, importing or manufacturing passenger vehicles in the United States, citing job, economic and national-security risks. Six industry groups led by the Alliance for Automotive Innovation sent a Sept. 17 letter before Trump's planned meeting with Chinese President Xi Jinping, warning that Chinese vehicle market access could become a trade-negotiation issue. Chinese automakers are largely excluded by steep tariffs, procurement restrictions and connected-vehicle rules, though the industry is also watching possible indirect entry through Mexico. The lobbying follows Trump's past openness to Chinese carmakers building US plants with American workers.
