"If it were to happen, we have a plan, but ideally it would not happen," the Mexican president responded to a specific question on the subject.

Mexican President Claudia Sheinbaum said Friday morning that the Aztec country has a plan in case U.S. President-elect Donald Trump imposes tariffs on crude oil exported from Mexican lands.

"If it were to happen, we still have a plan, but ideally it would not happen," Sheinbaum responded to a specific question on the subject.

Most of state oil company Pemex's oil exports are destined for the U.S. market. The U.S. accounts for 61% and 56% of Canadian and Mexican crude exports, respectively, according to Kpler ship-tracking data.

Trump said Monday he would impose a 25% tariff on imports from Canada and Mexico until they crack down on drugs, particularly fentanyl, and migrants crossing borders illegally.

The measure does not exclude crude oil, Reuters reported.
