Politics is rarely about what happens on camera. It's about the paper trail. Specifically, the Mexico president letter to Trump stands as one of the most fascinating examples of how two leaders, who couldn't be more different on paper, managed to navigate a relationship that many predicted would be a total train wreck.
It wasn't just one letter, actually. Over the years, Andrés Manuel López Obrador (AMLO) and Donald Trump exchanged several pieces of correspondence that defied the usual "diplomatic speak." While the media was focused on the "Build the Wall" rhetoric, the actual text moving between Mexico City and Washington D.C. told a much weirder, much more pragmatic story.
You've got to understand the vibe back then. People expected fireworks. Instead, they got a strange kind of mutual respect that was anchored in some very specific, very blunt letters.
Why the Mexico president letter to Trump actually worked
Most people think international relations are handled by guys in suits whispering in hallways. Sometimes, it’s just a bold letter. When AMLO won the Mexican presidency in 2018, he didn't wait for an invite. He sent a seven-page letter to Trump. He didn't use flowery language. He talked about "development" and "migration" as if he were talking to a business partner, not a king.
It was a gamble. Honestly, it shouldn't have worked.
Trump was literally campaigning on the idea that Mexico was an adversary. But AMLO’s letter took a different tack. He focused on shared interests—specifically the economy and reducing migration through investment rather than just force. This Mexico president letter to Trump set the stage for what became a surprisingly stable period in U.S.-Mexico relations. AMLO basically told Trump, "Look, we both want the same thing: a stable border and a strong economy. Let's stop shouting and start trading."
It’s kind of wild when you think about it. AMLO is a leftist populist. Trump is a right-wing populist. On paper, they should have hated each other. But the letters show they spoke the same language of "nationalism first." They both viewed the world through a lens of sovereignty.

The 2018 Pivot
In that initial 2018 letter, AMLO wrote about his plan to make Mexico so prosperous that "no one will want to leave." He was selling a dream. He knew Trump liked big ideas and "deals." By framing migration as an economic issue rather than a human rights one, he found a way into Trump's good graces.
The letter also touched on the North American Free Trade Agreement (NAFTA), which was being renegotiated into the USMCA. AMLO used the letter to signal that he wasn't going to be a thorn in the side of the trade deal. He wanted it done. He wanted certainty. Trump respected that.
The Tariff Threat and the Letter That Saved the Deal
Things weren't always smooth. Remember 2019? That was the year Trump threatened to slap a 5% tariff on all Mexican goods unless the country stopped the flow of migrants. The Mexican economy was looking at a potential freefall.
In response, AMLO sent another Mexico president letter to Trump. This one was different. It wasn't just a proposal; it was a plea for "dialogue." But it was also firm. AMLO wrote, "I do not believe in the 'eye for an eye' philosophy." He called for a meeting in Washington.
The letter worked because it didn't escalate the fight. It gave Trump a "win" by showing that Mexico was taking the threat seriously.
Within days, a Mexican delegation led by Marcelo Ebrard was in D.C. They hammered out a deal that involved Mexico deploying its newly formed National Guard to the southern border. Many activists in Mexico were furious. They felt AMLO had sold out. But from a purely pragmatic standpoint, that letter and the subsequent deal prevented an economic catastrophe. It’s a classic example of how a well-timed piece of correspondence can change the course of a country's GDP overnight.

What Most People Get Wrong About the Content
There’s this misconception that these letters were full of secret concessions. They weren't. If you actually read the transcripts and the declassified versions, they are surprisingly straightforward.
- They focused on Infrastructure: AMLO kept pushing for a "Marshall Plan" for Central America.
- They avoided Ideology: You won't find mentions of socialism or capitalism.
- They used Personal Flattery: AMLO often referred to Trump’s "understanding" of the situation.
It’s also important to realize that the Mexico president letter to Trump wasn't just for Trump’s eyes. These letters were often leaked or published by the Mexican government almost immediately. Why? Because AMLO needed his domestic audience to see that he wasn't being bullied. He wanted to look like a peer, not a subordinate.
The Contrast with Claudia Sheinbaum
Fast forward to the present. With Claudia Sheinbaum now in power and Trump back in the headlines for the 2024 and 2028 cycles, the playbook is changing. Sheinbaum has already sent her own letters and messages. But the tone is different. It’s more clinical. More academic.
When Trump started talking about 25% tariffs again recently, Sheinbaum’s response was a public letter that mirrored the AMLO style but added a layer of modern economic reality. She pointed out that U.S. companies like GM and Ford would be the ones suffering. She basically said, "If you tax us, you're taxing your own people."
The Legal and Diplomatic Reality
Letters between heads of state aren't just polite notes. They are "state papers." They are archived. They are studied by intelligence agencies for tone, word choice, and what isn't said.
When the Mexico president letter to Trump was sent, the U.S. State Department had to analyze it alongside the White House. There was often a disconnect. The career diplomats were worried about protocol, while Trump and AMLO were basically texting through formal channels.

This led to some weird situations. For example, during the "Remain in Mexico" (MPP) negotiations, the letters provided a "paper trail of plausible deniability." Both sides could claim they were doing what was best for their own people while actually collaborating on a very controversial border policy.
Actionable Insights for Understanding the Modern Relationship
If you're trying to track where U.S.-Mexico relations are headed, stop looking at the tweets. Look at the formal letters. They are the true north of diplomacy.
First, look for the "Economic Hook." Any letter from Mexico to a U.S. president that doesn't mention trade is probably just fluff. The real meat is always in the USMCA and supply chains.
Second, watch the "Sovereignty Language." Mexico is incredibly sensitive about its independence. If a letter starts talking about "mutual respect for sovereignty," it’s a signal that Mexico is about to draw a hard line on something, probably energy or fentanyl.
Third, pay attention to the "Regional Approach." Mexico likes to position itself as the leader of Latin America. In the Mexico president letter to Trump, AMLO often spoke on behalf of the region, trying to convince the U.S. that fixing the "root causes" of migration was cheaper than building a wall.
Next Steps for Staying Informed
To really get the pulse of this, you should follow the Mexican Ministry of Foreign Affairs (SRE) website. They often publish the full text of these letters in Spanish. Use a high-quality translator to see the nuances. English news summaries often miss the specific cultural idioms that AMLO or Sheinbaum use to signal strength to their voters back home.
Also, keep an eye on the "High-Level Economic Dialogue" (HLED). This is where the promises made in those letters actually get turned into policy. It’s less dramatic than a letter to the president, but it’s where the money moves.
Ultimately, the Mexico president letter to Trump was a masterclass in "Strongman Diplomacy." It showed that even when two countries are at odds, a direct, blunt, and somewhat respectful line of communication can prevent a total collapse. It wasn't about friendship. It was about survival.
