Former US president Bill Clinton has used his visit to Northern Ireland earlier to promote the prospect of American investment in the region.
His two-day trip to attend events in Ireland north and south comes ahead of a major Northern Ireland investment conference in Washington next month to be hosted by Hillary Clinton.
Mr Clinton will be in Londonderry to meet business leaders currently lobbying to build economic links across the Atlantic.
He may also use the visit as an opportunity to honour the contribution of former SDLP leader John Hume to the peace process.
The former president will meet First Minister Peter Robinson and deputy First Minister Martin McGuinness at the University of Ulster's Magee College where he will deliver a keynote address to an invited audience.
Mr Clinton will travel on to Dublin after the engagement where he will open the Clinton Institute for American studies at University College Dublin.
The economic summit organised by US secretary of state Hillary Clinton will take place on October 19 in Washington DC.
