Taoiseach Simon Harris and Welsh First Minister Eluned Morgan agree to review progress around repairing Holyhead port in the new year.
The busy ferry port in Anglesey, North Wales, was forced to close following damage during Storm Darragh and is not set to reopen until 15 January at the earliest.
All ferry services between Dublin and Holyhead are currently cancelled, upending travel plans for thousands in the festive season.
Taoiseach Simon Harris spoke with his welsh counterpart about the impact of the ongoing closure of the port on the movement of both people and freight between Ireland and the UK.
It is understood that both leaders acknowledged the ongoing efforts being made on both sides to ensure that people travelling home for Christmas are able to do so.
They also discussed the importance, in all scenarios, of ensuring sufficient port capacity to maintain the supply chains vital to both economies, and agreed to speak again in the New Year to review progress.
The Taoiseach said they spoke of the need to find workable alternatives while Holyhead remains closed.
"The closure of Holyhead port has caused a lot of heartache and disruption for people and traders this Christmas," Mr Harris said.
"I took the opportunity this afternoon to take stock of the situation with the First Minister of Wales, Eluned Morgan.
"We discussed the importance to both Wales and Ireland of ensuring sufficient port capacity to support vital supply chains between Ireland and the UK, and the need to find workable alternatives for as long as Holyhead remains out of commission.
"We expressed a shared wish to see Holyhead return to operation in January, and we agreed to speak again in early January to review matters at that point," the Fine Gael leader added.
