Mexico City, July 23 (EFE-RHC) -- The Mexican government expressed its "concern" over the decision by Texas authorities to send 1,000 National Guard troops to the border to help stem the massive arrival of undocumented child migrants from Central America.

"Attention to the immigration phenomenon must be paid from a long-term regional perspective and based on the principles of good neighborliness and shared responsibility," the Foreign Relations Secretariat said in a statement.

The secretariat declared its commitment to the protection of the migrants' human rights and the orchestration of "specific actions directed at the most vulnerable, including unaccompanied children and teenagers."

The secretariat emphasized that Mexico had opted for a strategy favoring dialogue and cooperation, and it is working "with the countries of Central America to improve conditions in the medium and long term that contribute to the development of that region and strengthen its prosperity."

More than 57,000 unaccompanied immigrant minors have entered the United States via the border with Mexico over the past 10 months, most of them coming from Central America, a situation that has spurred the governments of the region to try and halt what has been described as a humanitarian crisis.
