Mexican Foreign Minister Luis Videgaray said on Monday that Mexico decides its immigration policy in a sovereign manner. Videgaray added that it would be “unacceptable” to condition the renegotiation of the North American Free Trade Agreement to the issue, Reuters said. The minister’s comments on Twitter came after US President Donald Trump threatened to make immigration control a condition of a new NAFTA deal. According to the president, Mexico must stop illegal immigrants from getting into the United States. “Mexico, whose laws on immigration are very tough, must stop people from going through Mexico and into the US. We may make this a condition of the new NAFTA Agreement,” Trump tweeted.
