The government of Mexico has said it will review all cooperation with the United States.
In a brief statement on Monday, the Mexican government said President Enrique Peña Nieto instructed ministries at a cabinet meeting on Sunday to evaluate "mechanisms of cooperation" with the US government.
Foreign Minister Luis Videgaray said on Twitter the evaluation would take place in coordination with his ministry and covered all current cooperation. The statement did not give details on the reasons for the order, but an official familiar with the matter said it should be seen as a sign of Peña Nieto's increasing frustration with his counterpart Donald Trump's attitude towards Mexico.
Peña Nieto scolded the Trump administration on Thursday after Trump said he would send National Guard troops to beef up the southern border. Mexico's plan to review all cooperation with the US took shape after Trump accused Mexico of failing to stop a "caravan" of Central American migrants organized by a human rights group traveling toward the US border. However, the caravan quickly began dispersing when Mexican authorities moved in to register the migrants.
Trump, who launched his election campaign by threatening to build a wall to keep the Mexicans out and referring to them as rapists, has caused great anger in Mexico, and Pena Nieto, who has one of the lowest approval ratings of any modern Mexican president, has tended to be on the good side of Mexicans by taking a stand against Trump.
