Initial improvements: The U.S. has officially renamed the Gulf of Mexico to the Gulf of America and changed the name of Alaska's highest mountain.

In the United States, the Mexican Gulf has been renamed to the American Gulf, as stated on the country’s Department of the Interior website.

“According to President Donald Trump’s decree, the Mexican Gulf will now officially be called the American Gulf, and the highest peak in North America will once again bear the name Mount McKinley,” the department reports, as cited by Reuters.

The changes aim to preserve the heritage of the United States and “ensure that future generations of Americans honor the legacy of heroes and the historical values of the country,” the Interior Ministry’s website also mentions.

It is noted that the gulf is of “central importance to the nation” as it serves as “the most vital artery for American trade, energy production, and the maritime industry.”

William McKinley, who served as President of the United States from 1897 to 1901, “made our country very wealthy through tariffs and talent – he was a born businessman,” Trump remarked.

“They took his name from Mount McKinley,” Trump said. “He was a great president.” Trump promised that his administration would “restore the name Mount McKinley because, in my opinion, he deserves it.”

The mountain in Alaska was named in honor of McKinley in 1917; however, in 2015, by the decree of then-President Barack Obama, the peak was renamed Denali at the request of the indigenous people – in their language, it means “high”.

The renaming of the Mexican Gulf is unlikely to be recognized internationally, Reuters notes. Mexico, which, like the United States, borders the gulf, has stated that the internationally recognized name has been used in maritime navigation for hundreds of years.

The U.S. Board on Geographic Names is “actively working on updating the official federal nomenclature,” the Department of the Interior reported, where the board is located.

Previously, Mexican President Claudia Sheinbaum responded to Trump’s initiative by stating that “for us and for the whole world, the gulf will still be called the Mexican Gulf.”

Sheinbaum jokingly suggested renaming part of North America, which includes a significant territory of present-day U.S., to “Mexican America,” as it was on maps from 1607.

Background. Meanwhile, it became known that Trump had a tough conversation with Prime Minister Frederiksen regarding the purchase of Greenland. Trump “threatened with specific economic measures, such as targeted tariffs.”
