The DUP has welcomed moves by the Irish Government to spend billions of euros in the North as part of the latest National Development Plan.
The €184bn plan includes funding of around €1.2bn for projects north of the border.
DUP deputy leader Peter Robinson responded yesterday by saying any contribution to making the North more economically competitive was a good thing.
He also said his party was happy to work with the Irish Government on matters of mutual benefit.
Mr Robinson said the planned spending posed no risk to the North's sovereignty or constitutional status and the DUP would have the right to vet each project proposed under the NDP.
