It was a historic moment for Mexico: the first time workers were given the right to vote on a labor contract negotiated by their union under a new law.

Mexico’s Senate ratified a North American trade deal with the U.S. and Canada, becoming the first to do so amid a truce reached with President Donald Trump over an unrelated tariff threat.

Mexico’s top trade negotiator said he was heartened by a retreat from more protectionist rhetoric in the United States and that talks to redo the North American Free Trade Agreement may conclude as soon as January.
