Foreign-brand automakers with U.S. plants do not support Trump administration rules to raise the amount of local content in North American-made vehicles, a group representing companies including Toyota Motor Corp., Volkswagen AG and Hyundai Motor Co. has told key U.S. lawmakers.

Talks between Mexican Economy Minister Ildefonso Guajardo and U.S. Trade Representative Robert Lighthizer are due to resume Tuesday in Washington to try to resolve remaining bilateral issues so that Canada, which has been sidelined for weeks from the negotiations, can return to the bargaining table.

The automakers' position was in a previously unreported Aug. 16 letter from their "Here for America" group to top trade-focused members of Congress. The letter could raise resistance to a revamped North American Free Trade Agreement from lawmakers in southern states, where foreign manufacturers have built auto plants.
