The Mexican government announced on Wednesday it would increase "collaboration at the state and local level" in the United States regarding Mexican immigrants, suggesting some form of possible collusion with "sanctuary cities."

"Reinforce dialogue with local and state authorities, in the understanding that local policies determine, in good measure, the daily life of Mexicans in the U.S.," reads the Mexican government's plan to protect its citizens living in the United States after Donald Trump's election, reported The Hill.

Trump had made immigration and deportation and those living illegally in the United States as part of his platform during the presidential campaign but now mayors of "sanctuary cities" and some governors say they won't cooperate with federal officials in prosecuting non-criminal illegal aliens.

The 11-step plan called for Mexicans living in the United States to stay away from "situations of conflict" that could lead to arrest and then deportation, according to the Los Angeles Times.

Mexico's foreign ministry announced the plan in a statement titled "We Are With You," said The New York Times. The ministry urged immigrants to get accurate information about possible changes in U.S. immigration policy.

"Fellow countrymen, these are moments of uncertainty," Mexico Foreign Minister Claudia Ruiz Massieu said in a coordinated video. "Stay calm, do not fall to provocations and do not let yourself be deceived. We want to inform you about possible migratory actions."

While there is no legal definition of a sanctuary city or government, some have used the term to describe local and state governments that have policies or laws that limit the extent to which law enforcement and other government employees will go to assist the federal government on immigration matters, reported CNN.

In some sanctuary cities, police and other government employees are not allowed to ask a person's immigration status because crime victims and witnesses might be less likely to talk to investigators for feat of being deported, noted Fox News.

Sarah Saldana, director of the U.S. Immigration and Customs Enforcement, told Congress in March that there are more than 200 state and local jurisdictions that fall under the definition, noted CNN.

Despite Trump's threat during the presidential campaign to slash federal funding for sanctuary cities, some big city mayors have spoken out about their position in recent days, said Fox News.

"I would say to the president-elect, that the idea that you're going to penalize Boston, New York, Los Angeles, Chicago, San Francisco, Philadelphia – these are the economic, cultural, and intellectual energy of this country," Chicago mayor Rahm Emanuel said in a radio interview, per Fox News, proclaiming that Chicago will "always be a sanctuary city."

New York Mayor Bill de Blasio said he would destroy a database with the names of undocumented immigrants with city identification cards before turning them over to the Trump administration.

The Mexican government said in its statement that it will make it easier for Mexicans living in the U.S. to obtain proper Mexican identity documents and will intensify a campaign to register as Mexican citizens children born in the U.S. to parents who are Mexican nationals, reported the Los Angeles Times.
