The Minister for Foreign Affairs, Mr Cowen, will meet Northern Secretary Mr Paul Murphy in Belfast today ahead of next Thursday's expected Hillsborough summit.
The summit, to be hosted by the British Prime Minister Mr Tony Blair, and the Taoiseach, Mr Ahern, will see the two leaders unveil their proposals for implementing the Agreement in full.
Speculation has been mounting the Assembly poll could be moved from May to October if parties reject the plan.
Last month, Mr Murphy moved the date of the Assembly elections to May 29th to give the pro-Agreement parties more time to accept the governments' blueprint.
Ulster Unionist Party leader Mr David Trimble said yesterday he plans to put any "acts of completion" deal to restore Northern Ireland's devolved government to a meeting of the Ulster Unionist Council on April 26th.
