The Mexican government is criticizing Donald Trump's policy proposals on immigration, border security and U.S.-Mexico relations.

The Foreign Relations Department says the GOP candidate's stances "reflect prejudice, racism or plain ignorance."

Trump this week outlined proposals to deny citizenship to U.S.-born babies of immigrants living in the United States illegally as part of a plan emphasizing border security and millions of deportations. He also says he would build a wall along the U.S. southern border and force Mexico to pay for it.

The Foreign Relations Department said Wednesday that such proposals "are not only prejudiced and absurd," but would be harmful for both countries.

It said Mexican migrants make significant contributions to the U.S. economy and net migration from the country to the United States reached zero in recent years.
