Washington declined to approve a new 16-year USMCA extension at the July 1 review, keeping the pact in force for 10 more years unless a member exits while opening annual negotiations over major trade issues.
The United States, Canada and Mexico began the six-year USMCA review on July 1 with the Trump administration declining to approve a new 16-year extension and instead moving the pact into annual reviews. U.S. Trade Representative Jamieson Greer said Washington would not “rubber-stamp” the agreement because it sees “substantial issues,” while a senior administration official later confirmed the decision. USMCA remains in force for another 10 years unless a member withdraws, but the move opens the door to yearly negotiations over major parts of the treaty, including automotive rules of origin, and adds uncertainty for North American supply chains amid unresolved disputes with Canada and ongoing U.S.-Mexico talks.
