Donald Trump has name checked Ireland as one of the countries which he believes has taken manufacturing jobs from America.
In comments made during a press conference in Trump Tower on Tuesday, the US President said he would like to see jobs "brought back" to the US.
Three executives from Intel, Merck, and Under Armour resigned from the American Manufacturing Council following Trump's initially tepid response to violence at a rally of white supremacists in Charlottesville at the weekend.
Mr Trump was questioned as to why the three executives - including Merck CEO and Intel CEO, two companies which have significant operations here - had quit the presidential council.
The US President singled out Ireland while criticising the actions of the three executives.
"We want products made in the country," he said.
"Now I have to tell you that some of the folks will leave, they're leaving out of embarrassment because they make their products outside.
"I've been lecturing them, including the gentlemen you're referring to, about you have to bring it back to this country (the US)."
"You can't do it necessarily in Ireland and all of these other places, you have to bring this work back to this country, that's what I want," he said.
"I want manufacturing to be back into the United States so that American workers can benefit."
When Merck chief Kenneth Frazier resigned on Monday, saying he was taking a stand against intolerance and extremism, Mr Trump responded with a tweet.
"Ken Frazier of Merck Pharma has resigned from President's Manufacturing Council, he will have more time to LOWER RIPOFF DRUG PRICES!," he said.
