A new programme of co-operation between Ireland and Wales, running to 2030, has been signed by Tánaiste Simon Harris and Welsh First Minister Eluned Morgan at the Ireland-Wales Forum in Swansea.
The forum was established in 2021 in the aftermath of Brexit to help strengthen ties between both countries.
It aimed to build on an Irish-Welsh regional cooperation agreement that operated when the UK was part of the EU, but which lapsed when the UK left the bloc.
Mr Harris said it was "a really important demonstration of our deep friendship between our two countries.
"We're near neighbours. We share common values. We share a sea, we share so much, and we want to work together in key areas where it makes sense, and we've been doing that for the last number of years".
Mr Harris and Ms Morgan signed a new programme of co-operation between both countries running to 2030.
Ms Morgan said it marked a "new phase" for the Ireland-Wales Forum.
"We're taking it to the next level now, making sure that we get more outcomes that will help to shape the lives of people in Ireland and in Wales, better jobs, better opportunities, making sure that those relationships are meaningful.
"You just saw this winter how the storm [Darragh] affected the way that goods were transported between Wales and Ireland. We've now got a strengthened cooperation around resilience, around our ports, making sure that we don't have a situation in future where there's a real threat to those movement of goods between our nations and people as well," she said.
Previous achievements from the forum include the Greenlink interconnector between Wexford and Pembrokeshire.
As part of the forum, Mr Harris and Ms Morgan will meet researchers at Swansea University, who are working with research colleagues in Cork and Limerick.
They will also meet energy company MaresConnect, which is building an interconnector between Wales and Ireland.
