Sheinbaum, who has walked a fine line with Trump to offset threats of tariffs and military action against cartels, provided few details.
She noted that private companies in Cuba, including hotels, "are looking for private entities willing to supply them with fuel," and that they have approached Mexico's state-owned oil company to purchase crude oil, adding that these requests are currently being reviewed.
Cuba has long been at the heart of a geopolitical tug-of-war between the U.S. and Russia, dating back decades. Trump on Sunday dismissed the idea that allowing the boat to reach Cuba would help Russian President Vladimir Putin.
"It doesn't help him. He loses one boatload of oil, that's all it is. If he wants to do that, and if other countries want to do it, it doesn't bother me much," Trump said on Sunday. "It's not going to have an impact. Cuba's finished. They have a bad regime. They have very bad and corrupt leadership and whether or not they get a boat of oil, it's not going to matter."
The U.S., the European Union and the United Kingdom sanctioned multiple vessels, including the Anatoly Kolodkin, used to carry Russian oil following the war in Ukraine.
