The Sinn Féin President has met the European Commissioner for Regional Policy as part of a series of meetings during a one-day visit to Brussels.
Gerry Adams held talks with Danuta Hubner on the possibility of future EU funding under the so-called Peace 3 initiative.
The last tranche of funds under Peace 2 came to nearly €600m over the period 2000 to 2006. That money has supported more than 5,000 projects on both sides of the border.
A spokesperson for Commissioner Hubner said she was well disposed towards an extension of Peace 3 by around €200m.
However, she said it was dependent on the resolution of the 2007-2013 EU budget round, negotiations which collapsed in June.
Mr Adams told a news conference at the European Parliament that he had come to explore how Europe could help advance the peace process.
Asked about the murder of Dublin man Joseph Rafferty, Mr Adams said that no one involved in Sinn Féin was involved in his killing.
Mr Adams said he had made it clear that the party repudiated the killing and would do everything they could to help the Rafferty family.
Earlier, Mr Adams dismissed as nonsense claims that the IRA has held back about 300 guns despite its commitment to a full decommissioning of weapons.
He said he fully accepted the report of the independent decommissioning body which had made it very clear that all IRA weapons were now beyond use.
His comments came after Unionist MEPs demanded that he state whether the IRA would end all criminal activity when he met a group of left-wing MEPs at the parliament today.
Jim Nicholson of the Ulster Unionists and the DUP's Jim Allister have reacted sceptically to Mr Adams' visit to the parliament.
The West Belfast MP faced questions on last week's announcement that the IRA has completed its disarmament programme at an event hosted in the parliament by Francis Wurtz, President of the United European Left-Nordic Green Left.
