Last year Mexico deported over 200,000 Central Americans that were only traveling through with no intention of staying in Mexico on their way to the USA. Mexico deported more Central Americans than did the US Immigration Service.
Things got so tough in Mexico that about three years ago the Mexican government deported 50 Mexican Oaxacans to Guatemala in the mistaken belief that they were Guatemalans from the San Marcos region.

I guess the Mexican government really only wants Mexicans to inherit America.
