Government ministers from Dublin, London and Stormont are to take part in their first international joint trade mission early next month.
Representatives from all three administrations are to attend the Singapore Airshow to pursue trade and investment opportunities in the aviation sector.
The delegation will be led by Minister for Jobs, Enterprise and Innovation Richard Bruton, his Northern Ireland counterpart Arlene Foster, and British Transport Minister Stephen Hammond.
It will also include representatives of companies from the three jurisdictions.
Afterwards, Mr Bruton will travel to Malaysia for a separate four-day trade mission.
The initiative, which emerged from discussions involving Taoiseach Enda Kenny and British Prime Minister David Cameron, comes two months before the first State visit by a President of Ireland to Britain.
Speaking as he arrived at today's Cabinet meeting, Tánaiste Eamon Gilmore said the trade mission was part of ongoing and increased cooperation between the countries on economic matters.
Mr Gilmore said aviation was one area where Dublin, London and Stormont could produce better results by working together.
