During the 1970s and 1980s Mexico opened its doors to immigrants from Latin America, mainly political refugees from Chile, Cuba, Peru, Colombia and Central America. The PRI governments, in power for most of the 20th century, had a policy of granting asylum to fellow Latin Americans fleeing political persecution in their home countries. A second wave of immigrants has come to Mexico as a result of the economic crises experienced by some countries in the region. The Argentine community is quite significant estimated to be somewhere between 11,000 and 30,000.
