“The United States did not agree to renew the USMCA in its current form. As a result, the USMCA is not renewed,” Greer said in a statement.
The refusal did not tear up the pact, which stays in force while the three governments begin annual reviews that could run until it expires in 2036. A renewal on Wednesday would have reset that clock to 2042 and spared businesses a decade of recurring uncertainty.
The agreement replaced the North American Free Trade Agreement in 2020 and covers a market worth about US$1.8 trillion a year. It supports an estimated 17 million jobs and allows parts and products to cross the three borders without tariffs.
Its rules reach deep into industry, requiring 75 per cent of a vehicle’s content to originate in North America to move duty-free. That binds together supply chains in which parts cross the borders repeatedly before a finished car is sold.
