U.S. Secretary of State Mike Pompeo met with his Mexican counterpart Marcelo Ebrard on Sunday near the end of a Latin American tour and at a key moment for U.S.-Mexico relations.

Pompeo arrived by caravan to the Foreign Relations Ministry in central Mexico City in the morning and left without making public comments, though the department released photos and soundless video of the two men shaking hands and talking at a table. The encounter was not open to journalists.

The meeting between Pompeo and Ebrard came at the halfway point of a 90-day span during which Mexico has agreed to reduce migration through its territory toward the U.S. border as part of a deal that headed off stiff tariffs on Mexican goods threatened by U.S. President Donald Trump.

Since then, Mexico has stepped up immigration enforcement, while the United States has expanded to two more border points a program sending asylum seekers back to Mexico to await the outcome of their claims.

The ministry said in a statement Sunday that Pompeo recognized that Mexico has made "significant" progress on migration enforcement.

Mexican officials say they have increased migration enforcement along the southern and northern borders, while deporting hundreds of Central Americans each week by plane. Mexico is also allowing applicants for asylum in the U.S. to await their hearings from Mexico.

Ebrard said that due to these advances, Mexico sees no need to negotiate a "third safe country" agreement with Washington that would require migrants to apply for asylum in Mexico rather than the U.S. 

As the motorcade carrying Pompeo departed Sunday, a lawyer for convicted drug lord Joaquin "El Chapo" Guzmán jumped in front of a vehicle with a hand-painted sign that read: "Chapo's Money, No USA, Yes Mexico."

A U.S. judge ordered Guzmán to pay $12.6 billion as part of his U.S. life sentence  announced Wednesday. 

President Andres Manuel López Obrador said Thursday the money is Mexican, and that he will seek its return to the country by legal means, if necessary.

The driver of a black Suburban tapped Guzmán's lawyer three times with the front grill of the SUV before a Mexican official pulled the lawyer away.

Speaking to reporters, lawyer Jose Luis González said Guzmán wants his money to be distributed among Mexico's poor, rather than confiscated by the U.S. government. The lawyer is also fighting for Guzmán's extradition back to Mexico.

The ministry said that Ebrard suggested that the U.S. and Mexico work together to recover Guzmán's assets. Also, Ebrard asked for help to stem the flow of weapons trafficked into Mexico from the U.S.

Pompeo was to travel to El Salvador later Sunday and meet with President Nayib Bukele.

Bukele said last week that his country is trying to reduce irregular migration and fight crime and drug trafficking, and deserves to be considered differently than neighboring Guatemala and Honduras.

Those three countries make up Central America's so-called Northern Triangle, the source of most of a wave of migrants and asylum seekers who have sought to make it to the United States this year, fleeing violence and poverty back home.
