Mexico’s President Claudia Sheinbaum is confident that her country can reach a deal with the U.S. to avoid the 25% tariff threatened by U.S. President-elect Donald Trump, she told reporters in Mexico City.

The U.S.’s No. 1 trade partner has a plan if Trump does impose tariffs but Sheinbaum — who spoke with the president-elect on the phone on November 27 — says she doubts it will be necessary to implement. Instead, she said Mexico and the U.S. can collaborate in the face of Trump’s concerns on migration and drug-trafficking. She insisted that Mexico would not be subordinating itself to the U.S. by doing so.

“I’m convinced we’re going to reach an agreement, while defending our sovereignty, with respect for Mexicans and respect for Mexico, with the collaboration that one government should have with another,” Sheinbaum said. “If it does happen, we do have a plan. But the goal is for it not to happen.”
