Mexico’s Ministry of Foreign Affairs is concerned about an influx of immigrants into the country from African and Asian countries, according to a report Thursday in El Universal.

“Many of them will have to return to their home countries,” Socorro Flores, undersecretary of Latin America and the Caribbean for the Mexican Foreign Ministry, said to El Universal.

The Mexican government is now trying to deal with this influx of immigrants by setting up shelters and working with the countries of origin of the immigrants on deportations.

Flores said regarding this immigration that, “yes there is a concern because the flows have increased and there is also a concern because they need to cross many countries to get to their intended destinations.”

The government official added, “right now they are coming from many countries in Asia and Africa and that increases regional migration.”

Central America has recently been dealing with an influx of immigrants from abroad. It was recently reported that Guatemala has caught 56 times more African immigrants in 2016 than they did in all of 2015. These immigrants frequently have the goal of heading to the United States and seeking asylum.

Flores said that tackling this immigration issue will take time and cooperation among Central American countries.
