A short-term plan to rapidly stem immigration from Central America is "going well," said Mexican President Andres Manuel Lopez Obrador on Wednesday.

"We are fulfilling the commitment we made with the government of the United States," Lopez Obrador said during his daily press conference.

Mexico has pledged to significantly reduce the number of mostly undocumented migrants reaching the U.S. border in 45 days.

Lopez Obrador welcomes U.S. President Donald Trump's recent decision not to apply punitive tariffs on Mexican imports for now, due to measures taken by Mexico.

In May, the number of U.S.-bound migrants entering Mexico reached a 10-year high.

Starting from June 7, at Trump's request, Mexico implemented stricter control on its southern border to curb the sudden surge of Central Americans crossing the country to reach the United States.

A report released Tuesday by Mexico's Foreign Affairs Ministry showed the number of migrants detained by the United States decreased in June.

Mexico is spearheading a medium- to long-term plan to address the causes of mass immigration, such as poverty and violent crime, by promoting investment in development programs in Honduras, Guatemala and El Salvador.
