Taoiseach Brian Cowen is set to travel to Armagh to discuss the economy with his Stormont counterparts.
Mr Cowen will lead a delegation at the Eleventh Plenary Meeting of the North South Ministerial Council.
He said important economic issues that affected the daily lives of everyone in Ireland and how both administrations would co-operate would be discussed at the event.
"Now, more than ever, we are committed to work together for economic recovery and a brighter future on this island," said Mr Cowen.
The meeting will be held in the new headquarters of the Joint Secretariat to the North South Ministerial Council and will be hosted by Peter Robinson and Martin McGuinness.
Later, the new headquarters will be officially opened by the Taoiseach, the First Minister and Deputy First Minister.
Mr Cowen added: "I have been honoured to be able to participate in all 11 plenary meetings of the North South Ministerial Council which have taken place since the Good Friday Agreement.
"The opening of the NSMC Joint Secretariat offices here in Armagh is another significant event which reflects the enormous and historic transformation in the politics of this island in recent years."
