Haiti has denounced what it said were "racist" remarks from former US President Donald Trump.

Trump said that migrants entering the US from Haiti would put Americans at risk of contracting AIDS.

"So we have hundreds of thousands of people flowing in from Haiti. Haiti has a tremendous AIDS problem," Trump said in an interview on Fox News.

"Many of those people will probably have AIDS, and they're coming into our country and we don't do anything about it, we let everybody come in," he said. "It's like a death wish for our country."

The Haitian embassy in Washington condemned the "racist and baseless statement about Haitian migrants, in particular, and the Haitian population, in general, of Donald J Trump."

"These vile comments aim only to sow hatred and discord against immigrants," the embassy said in a statement Friday.

The mid-September arrival of more than 30,000 migrants, mostly Haitians, who camped out for days under a bridge on the border between Mexico and Texas, has brought US President Joe Biden's administration under fire from Republicans. 

Over the course of less than three weeks, more than 7,500 Haitian migrants have been deported by US migration services.

After Trump's comments, the Haitian embassy said that "civilized people... should not remain indifferent to this umpteenth denigration of the Haitian people by former President Trump."

Two weeks ago, US special envoy to Haiti resigned, two months after his appointment, in protest against the expulsion of Haitian immigrants and their deportation to their country by Biden's administration.
