Mexico’s president trolls Trump with map of “Mexican America” ​​after his proposal to change name to “Gulf of America.”

Mexican President Claudia Sheinbaum responded sarcastically on Wednesday to US President-elect Donald Trump’s proposal to change the name of the Gulf of Mexico to “American Gulf”.

Standing in front of a 17th-century world map at her daily press briefing, Sheinbaum drily suggested that North America be renamed “América Mexicana,” or “Mexican America,” because the 1814 founding document, which preceded the Mexican constitution, called it that.

“That sounds nice, doesn’t it?” she added in a sarcastic tone. She also noted that the Gulf of Mexico has been called that since 1607.

Trump made the comments during an open press conference at Mar-a-Lago during which he also didn’t turn it off using military or economic coercion to bring Greenland and the Panama Canal under US control.

“We’re going to change the name of the Gulf of Mexico to the American Gulf, which has a beautiful ring to it,” Trump said. “It covers a large territory, the American Gulf. What a beautiful name. And it’s appropriate. It’s appropriate. And Mexico must stop allowing millions of people to pour into our country.”

Trump ally Republican Rep. Marjorie Taylor Greene of Georgia said she would introduce legislation in that sense on Thursday morning.

The exchange began to answer a broader question lingering over the bilateral relationship between the two regional powers: How would the newly elected Sheinbaum deal with Trump’s tough diplomatic approach and promises of mass deportations and crippling taxes on trading partners like Mexico?

Sheinbaum’s predecessor and political mentor, Andrés Manuel López Obrador — who came from a similar vein of class populism as Trump, though he leaned left — managed to build a relationship with Trump as an ally, and his government began blocking migrants from going north under pressure from the US -a, a boon for Trump.

But it was unclear whether Mexico’s first female president, a scholar and leftist who lacks the populist populism that brought López Obrador to power, would be able to build the same relationship.

While Wednesday’s prank quickly spread on social media, it also set the tone for what the Sheinbaum-Trump relationship could look like in the coming years.

“Humor can be a good tactic, it projects strength, which Trump responds to. That was probably the right choice on this issue,” said Brian Winter, vice president of the New York-based Council of the Americas. “While President Sheinbaum knows it won’t work on everything — Trump and his administration will demand serious engagement from Mexico on the big issues of immigration, drugs and trafficking.”

It comes after other sharp but cooperative responses from Sheinbaum regarding Trump’s proposals.

On Trump’s proposal to impose tariffs of 25%. on Mexican imports, Sheinbaum warned that if the new US administration imposed tariffs on Mexico, her administration would respond with similar measures. She said any kind of tax “is not acceptable and would cause inflation and job losses for the United States and Mexico.”

She has taken a more concessionary tone on immigration, in line with years of Mexican efforts to block migrants from making their way north amid mounting U.S. pressure

After initially saying her government would push the Trump administration to deport migrants directly back to their countries, she said in January that Mexico would be open to accepting deportees from other countries, but Mexico could limit it to certain nationalities or ask for compensation.

Canada also gave a sarcastic reply this week to Trump’s recent comments about annexing America’s northern neighbor. According to Canada’s CTV NewsOntario Premier Doug Ford was questioned by a reporter on Monday about Trump’s multiple threats impose a 25% tariff on products from Canada and Mexico in the early hours of his presidency, as well as by making Canada the “51st country”.

“You know what, I’m going to make a counteroffer to the president. How about we buy Alaska and throw in Minnesota and Minneapolis at the same time,” Ford said.
