Apparently you didn't follow the news too well at that time because it was widely published. Here's from CNN: (sweet aren't they ---they don't help them by improving their country but they prepare them kits to leave)
The new plan is to issue survival kits to would-be migrants. The kits, put together by the Mexican Social Security administration, include antidotes for snake bites, rehydration tablets, first-aid materials and dried foods to use on protracted crossings.
"We know their health needs, we know their education issues. We understand," said Juan Hernandez, of the Mexican Presidential Office for Mexicans Abroad.
Beginning June 18, some 200,000 kits will be distributed by health workers along the border.
