US president Donald Trump has confirmed he will visit Ireland later this year.
Mr Trump told Leo Varadkar that he wanted to make the trip during a meeting with the Taoiseach in the Oval Office in the White House on Thursday.
Mr Varadkar is on his annual St Patrick's Day tour to the United States.
Mr Trump said: "I am coming at some point during the year. I missed it last time and I would've loved to have been there. It's a special place and I have a very warm spot for Doonbeg, I will tell you that, and it's just a great place."
One of Mr Trump's golf courses is in the Co Clare village of Doonbeg.
The Taoiseach presented the US president with a bowl of shamrock to mark his St Patrick's visit to Washington DC. The bowl presented to Mr Trump, in the company of his wife, Melania, was made at Kilkenny Crystal in Callan, the home town of Irish-American architect James Hoban. Mr Hoban designed both Leinster House in Dublin and the president's official residence, the White House.
Mr Varadkar said: "The American economy is booming. More jobs. Rising incomes. Exactly what you said you'd do. However, I believe the greatness of America is about more than economic prowess and military might.
"It is rooted in the things that make us love America - your people, your values, a new nation conceived in liberty. The land and the home of the brave and the free."
The Taoiseach added that the futures of the US and Ireland were entwined.
"I believe that future generations of our citizens should have the same opportunity to enrich one another's societies as past generations have," he said.
Mr Trump, who was joined on stage by US vice president Mike Pence, said that millions of Americans across the country celebrate the "inspiring" Irish people on St Patrick's Day.
He also welcomed the Taoiseach's partner Matt Barrett, who also attended the event.
Mr Trump added: "I know many Irish people and they are inspiring, they're sharp, they're smart, they're great and they are brutal enemies so you have to keep them as your friend. Always keep them as your friend.
"You don't want to fight with the Irish, it's too tough, it's too bloody."
He reminded the crowd that the shamrock tradition began almost 70 years ago when Ireland's first ambassador to the United States, John Hearne, gave then US president Harry Truman a small box of it. He added that he accepted the gift as a symbol of America's "enduring friendship" with Ireland.
"The Irish are confident and fearless. They never give up, they never give in," he added.
Earlier, the US president said Brexit was "tearing countries apart".
The president, who set out his hopes for a "large scale" US-UK trade deal, added that: "I'm not sure anybody knows" what was happening with Brexit.
"It's a very complex thing right now, it's tearing a country apart. It's actually tearing a lot of countries apart and it's a shame it has to be that way but I think we will stay right in our lane," Mr Trump said.
The two leaders discussed Brexit as well as a number of Irish-US specific matters. Afterwards Mr Varadkar said he had a "really good meeting" with President Trump.
"We spoke about Brexit. Needless to say we have very different views on Brexit as to whether it's a good thing, but it was a real opportunity for me to set out Ireland's position, particularly when it comes to protecting the peace process and the Good Friday Agreement and protecting the border."
Mr Varadkar also said the leaders spoke about the issue of the undocumented Irish in the US.
"We talked about immigration. Very strong support from the president around the issue of securing more visas for Irish people to come and work here in the US, and (to) help us solve the issue of tens of thousands of Irish people who came here a long time ago but are undocumented," the Taoiseach said.
Earlier on Thursday US vice-president Mike Pence confirmed he was also planning a trip to Ireland with his mother Nancy. Mr Pence made the comments at a breakfast meeting with Mr Varadkar and his partner at the vice-president's residence in the capital.
During the meeting Mr Varadkar said that he is not judged by his sexual orientation but by his political actions.
"I stand here leader of my country, flawed and human but judged by my political actions and not by my sexual orientation, my skin tone, gender or religious beliefs." Mr Varadkar added: "I don't believe my country is the only one in the world where this story is possible. It's found in every country were freedom and liberty are cherished. We are, after all, all God's children. And that's true of the United States as well, the land of hope, brave and free."
