If Mexico were to assume "safe third country" status, asylum seekers would be required to claim refugee status in Mexico rather than the United States, and activists have long argued Mexico does not have the security conditions to offer safe haven for Central American migrants fleeing poverty and violence.
But she said they could not make any agreement on the issue, since they are not yet in government.
Andrés Manuel López Obrador, Mexico's president-elect, plans to implement a policy known as "Remain in Mexico" after taking office next month, his top domestic policy official told The Washington Post.

"Our very strong policy is Catch and Detain", he wrote in his Twitter message Saturday. The caravans will not be permitted to enter the United States.
Julieta Vences, a congresswoman with Lopez Obrador's Morena party who is also president of Mexico's congressional migrant affairs commission, told the AP that incoming Foreign Minister Marcelo Ebrard has been discussing with USA officials how to handle a deluge of asylum claims at the border.
