Tánaiste and Minister for Enterprise, Trade and Employment Leo Varadkar is in Washington DC for a series of high-level engagements on commerce and trade.

Later today, he will meet with the US Secretary of Commerce and the United States Trade Representative.

Earlier, he took part in a roundtable meeting with the US Chamber of Commerce and delivered an address to the Centre for Strategic and International Studies.

Asked if the US executives he was meeting were raising concerns about Ireland's corporate tax rate, he said they were interested to know the country's position on the matter.

"What I am saying to them is that it remains Ireland's view that tax is a sovereign competence and that it is up to each country to set its own tax rates. We are holding to that position but I am also saying that we are keen to be part of any international agreement if there is going to be one," he said.

"Whatever happens we are going to make sure that corporate taxes in Ireland remain low and that they (companies) have certainty going into the future so that if they make that 30-year multi-billion euro investment in Ireland they know that our rate is going to be considerably lower than it is in other countries and it is not going to go up and down," added Mr Varadkar.
