Politicians from both sides of the border attended a North/South Ministerial Council meeting in Dublin today.
The financial difficulties facing people on the island of Ireland dominated discussions at Farmleigh House.
Northern Ireland's First Minister Peter Robinson and Finance Minister Sammy Wilson were among those attending the meeting.
Mr Robinson said that all the institutions of the North/South Agreement are now working well and he emphasised the need for co-operation on financial matters.
Taoiseach Brian Cowen said that the two sides had discussed economic issues affecting everyone on the island.
He said that they would continue to work closely on financial matters, food and agriculture.
Earlier, Mr Cowen had said that the council can play an increasingly important part in the strategy for economic recovery.
It was set up under the Good Friday Agreement to develop consultation and co-operation within the island.
Today's meeting was the sixth held by the council and was attended by 26 ministers from both jurisdictions.
Elsewhere, President Mary McAleese met Mr Robinson and Mr Wilson this morning in Áras an Uachtaráin.
It was the first meeting between the President and Mr Robinson since he replaced Ian Paisley as DUP leader and First Minister two years ago.
