US Vice President Mike Pence is scheduled to visit Ireland in September.
The Vice President said that he would meet Taoism Leo Varadkar, Tanaiste Simon Coveney and President Michael D Higgins.
It will follow a visit to the UK "where it will focus on strengthening and expanding our bilateral economic relations" after Brexit.

A statement to the White House said that during his visit to Ireland, Mr. Pence would "express the commitment of the United States to maintain peace, prosperity and stability in Ireland by respecting the agreement Good Friday ".
In his tweet, Mr. Pence said: "On September 6 and 7, we will go to Ireland, a country very close to the heart of my family, where we can not wait to meet the President @MichaelDHiggins, Taoiseach @LeoVaradkar and Tánaiste @simoncoveney by celebrating my Irish roots! "
Nancy Pelosi, Speaker of the United States House of Representatives, confirmed the visit and announced that a trade agreement between the United Kingdom and the United Kingdom would not be dealt with by Congress if Brexit undermined Good Friday agreement.
"Whatever its form, Brexit can jeopardize the agreement on Good Friday, including the seamless border between the Republic of Ireland and Northern Ireland," said Wednesday Ms. Pelosi in a statement.
