Fourth formal USMCA negotiation round between the US and Mexico has been
postponed one week to Sept. 28-29 in Washington, originally scheduled for the
week of Sept. 21, the Wall Street Journal reports. The US is expected to push
Mexico for tighter rules-of-origin for AI equipment, household appliances and
medical devices to raise North American content and reduce non-North American
components entering the US market. Talks will also cover tariff adjustments for
steel, aluminum and autos as part of a US effort to tighten supply-chain rules
and accelerate nearshoring of critical industries.
