Cross-Border thinking when developing government policies will reap huge economic rewards, the SDLP will tell Dail deputies today.
A delegation led by the party's trade spokesman Dr Sean Farren will spell out their case for north-south integration to an Oireachtas committee on enterprise and small business.
Assembly members Dominic Bradley MLA and John Dallat MLA will also be at Leinster House for the talks.
"The North-South campaign which we launched last year has tapped into an enormous reservoir of goodwill among political parties, business and social partners in the Republic," said Dr Farren.
"The common objectives are agreed. What we now need to do is to put real shape on our ideas. "That is why we are asking the parties of democratic nationalism to bring forward the North South concept into all the decision-making forums, to help us integrate a full North South dimension into all the vital elements of decision-making in the Republic."
The SDLP MLA for North Antrim said talks at Stormont and elsewhere over the next few weeks will have a massive impact, for good or bad, on all the people of this island.
"There is widespread consensus on the great benefits that will flow from a stable political settlement, and there is a corresponding responsibility on the parties which continue to veto progress to consider the future of all our people. They know what has to be done. The time has come to do it," he said. end
