Mexico's incoming government says it does not plan to assume the role of "safe third country" for migrants seeking asylum in the U.S. after Andres Manuel Lopez Obrador is sworn in as president on Dec. 1.
Incoming Interior Minister Olga Sanchez says in a statement Saturday: "There is no agreement of any sort between the incoming Mexican government and the U.S. government."
She said the future government's principal concern related to the migrants is their well-being in Mexico.
The Washington Post reported Saturday that the administration of U.S. President Donald Trump has won support from the president-elect's team for asylum seekers to wait in Mexico while their claims move through U.S. courts.
Citing Mexican officials and senior members of president-elect Andres Manuel Lopez Obrador's transition team, the newspaper said the agreement would break with long-standing asylum rules and mount a new obstacle to Central American migrants attempting to reach the United States and escape poverty and violence.
Lopez Obrador has vowed to try to eliminate the causes of migration by creating more jobs and improving living conditions in Mexico and Central America.
In exchange, he hopes U.S. President Donald Trump and the Canadian government will agree to help spur economic development in the region.
Outgoing President Enrique Pena Nieto has also sought to stem the flow of migrants north by offering jobs to them, and has received backing from the private sector in his efforts.
Olga Sanchez Cordero, Mexico's incoming interior minister and the top domestic policy official for Lopez Obrador, who takes office Dec. 1, told the Washington Post the plan, known as Remain in Mexico, was a "short-term solution."
"The medium- and long-term solution is that people don't migrate," Sanchez Cordero said. "Mexico has open arms and everything, but imagine, one caravan after another after another, that would also be a problem for us."
The paper said that according to the outlines of the plan, asylum applicants at the border will have to stay in Mexico while their cases are processed, potentially ending the system Trump decries as "catch and release" that has until now generally allowed those seeking refuge to wait on safer U.S. soil.
Alison Leal Parker, U.S. managing director for Human Rights Watch, a legal rights organization, said the policy was "a pathetic attempt by the United States to shirk responsibility. Central Americans have faced serious harm in Mexico."
The effect, Parker said, would likely "push people fleeing for lives into riskier attempts to find safety, including using criminal human smugglers who will gain power under this new policy."
There was no immediate comment from the White House on the deal that the Washington Post said took shape last week in Houston during a meeting between Marcelo Ebrard, Mexico's incoming foreign minister, and top U.S. officials including Secretary of State Mike Pompeo and Homeland Security Secretary Kirstjen Nielsen.
Trump has been seeking to block thousands of Central Americans traveling in caravans from entering the United States, and has ordered that immigrants who enter the country illegally from Mexico are ineligible for asylum.
That order has been temporary suspended by a U.S. judge.
