A year after shifting production and sourcing out of China, some firms are finding it challenging to replicate the country's skilled labor, supplier networks, and reliable power elsewhere. U.S. retailer Target and Chinese fast-fashion retailer Shein are among those moving some operations or orders back to China. The tariff advantage of other countries has also narrowed as Washington extended tariffs to a wider range of nations. Businesses are watching for clarity on a proposed mechanism to lower barriers on some non-sensitive goods ahead of an expected meeting between Trump and Chinese President Xi Jinping this month, though many do not expect the summit to resolve their problems.
