Tourism Ireland head of business and sports tourism David Boyce said at a conference at the EIBTM show in Barcelona that the organisation plans to invest €1bn by 2012 in infrastructure required to attract corporate and association events to Ireland.
The money will be invested in promoting business and transport hubs including Dublin and Belfast.
Developments planned for 2010 include a new terminal at Dublin airport, Dublin Convention Centre, and the Aviva Stadium in Dublin

British business traveler numbers to Ireland fell 5% in the past year but the destination´s events visitors numbers remained steady, said Boyce.
"The extra business that we will get from the Dublin Convention Centre and the other developments will help business visitor numbers recover to their pre-recession levels," he said.
