Chinese exporters are using Cambodia to help sidestep American tariffs, the White House said, describing a process in which a nearly finished shirt made in China is sent to Cambodia, altered with a few stitches and then presented as Cambodian. The allegation goes to a broader concern around tariff evasion, where minor processing in a third country can change how goods are labeled for trade purposes. The White House says the practice undermines tariffs designed to protect U.S. manufacturing.
