Mexico’s Senate on Wednesday passed the USMCA, making it the first country to ratify the new North American trade pact.

“USMCA passes! Mexico goes first with clear signal that our economy is open,” Jesús Seade, Mexico’s undersecretary for foreign affairs, wrote on Twitter.

“We’re confident that our partners will soon do the same,” Seade added.

Passage in Mexico comes less than three weeks after Mexican President Andrés Manuel López Obrador’s administration submitted the required texts for Mexican lawmakers to approve the deal. The Mexican leader was forced to call an extraordinary session to consider the deal after it broke off for recess at the end of April.
