Mexico’s President Claudia Sheinbaum sent a letter to Google contesting the tech giant’s decision to comply with US President Donald Trump’s order to rename the Gulf of Mexico as the Gulf of America.

Sheinbaum made the case that Google should not bend to “the mandate of a country” attempting to change the name of an international sea. “For us it is still the Gulf of Mexico, and for the entire world it is still the Gulf of Mexico,” she said.

President Donald Trump has the power to rename the Gulf of Mexico to the Gulf of America, but whether people will call it that is an open question.
