Mexico's government may look for other trade partners, the nation's president said on Wednesday, after the United States slapped tariffs on its southern neighbor.

President Claudia Sheinbaum said that Mexico could shift trade alliances "if necessary," referring to the possible continuation of the tariffs.

U.S. President Donald Trump's new 25% tariffs on imports from Mexico and Canada took effect on Tuesday, along with fresh duties on Chinese goods, standing to seriously alter supply chains and long-standing trade partnerships.

Trump and Canadian Prime Minister Justin Trudeau are scheduled to speak on Wednesday, a source told Reuters. Sheinbaum is tentatively set to have a phone call of her own on Thursday with the U.S. leader about the tariffs, she said in her daily morning press conference.
