Taoiseach Micheal Martin is set to hold his first face to face meeting with British Prime Minister Boris Johnson in Northern Ireland today.
Today's meeting will be the first time the pair have met in person since Martin was elected as Taoiseach.
They are expected to consider the fight against coronavirus and work on a sustainable economic recovery as well as the UK's post-Brexit trade negotiations with the EU.
Mr Johnson said the pandemic had demonstrated the strength of the UK and that Westminster and Stormont have worked closely together to get through the crisis.
And he promised these close ties will continue.
"As the country begins to get back on its feet in the wake of coronavirus, we cannot simply strive to rebuild, but we must commit to building back stronger than ever.
"I cannot overstate how important the close co-operation that we have seen between central and devolved government will continue to be to this.
"Together, we will make sure Northern Ireland is ready to take full advantage of the many opportunities that lie ahead and that no part of Northern Ireland is left behind."
The Northern Ireland Executive will receive £2.2 billion (€2.4 billion) additional funding this year for its Covid-19 response.
It's expected Boris Johnson will also outline the first stage of plans to mark the centenary of Northern Ireland's foundation during his visit.
A forum and historical advisory panel will work alongside the British Government to commemorate the anniversary.
Northern Ireland was created in May 1921 following the partition of Ireland.
The Prime Minister said: "As we mark 100 years since the creation of Northern Ireland, it is important that we celebrate its people, culture and traditions, along with its vital contribution to the United Kingdom."
During his visit to Northern Ireland, the Prime Minister will also meet First Minister Arlene Foster and Deputy First Minister Michelle O'Neill to discuss how they can rebuild the economy.
