By "trade organisations", I take it that the Deputy is referring to the State agencies in the North which have responsibility for trade promotion, namely the Industrial Development Board and the local enterprise development unit.
Their counterpart in the South, An Bord Tráchtála, for which I have responsibility, has developed a good working relationship, involving regular contact, with the Industrial Development Board and Local Enterprise Development Unit. In recent years this contact has extended into organising programmes and events with the objective of developing North-South trade and bringing companies from all over the island together to create a stronger impact in overseas markets.
The Deputy might also wish to be aware that, at ministerial level, the development of cross-Border trade and the joint promotion of Irish products abroad were issues which I discussed with Baroness Denton, the Minister for Economic Development in Northern Ireland, when we met last week.
