China's 10 major foreign trade hubs, including Dongguan, Shenzhen, Shanghai, Guangzhou and Xiamen, have introduced a comprehensive package of countermeasures to address the challenges posed by recent U.S. tariff hikes, combining trade stabilization efforts with domestic consumption incentives. The coordinated regional response features Dongguan's supply chain resilience plan for key manufacturing sectors, Shenzhen's international market expansion initiatives for private businesses, Shanghai's commercial district upgrades to attract foreign spending, Guangzhou's domestic sales channel development for export-quality goods, and Xiamen's newly launched trade assistance hotline — all designed to help local enterprises navigate the changing global trade landscape.
