Chevron Corp. has begun using “Gulf of America” instead of “Gulf of Mexico” to describe the location of some of its largest oil operations, after President Donald Trump ordered the US to rename the body of water.

U.S. oil producer Chevron used the term "Gulf of America" instead of Gulf of Mexico in its fourth-quarter press release on Friday, a sign of corporate America beginning to implement U.S. President Donald Trump's order to rename the ocean basin.

One of US president Donald Trump’s first actions upon returning to power was ordering the Gulf of Mexico to be renamed. But mapmakers are still largely waiting for the green light.
