US President George W Bush has called for Turkey to be granted membership of the European Union.
Mr Bush was speaking as he attended his eighth and final summit with EU leaders in Slovenia.
Washington and European governments have played down the chance of dramatic announcements during the visit, which comes in the twilight of a presidency marked by fierce opposition from many Europeans to the US-led war in Iraq.
Divisions over Iraq have eased somewhat, as Europeans look past President Bush to his successor who will be elected in November.
Despite that, a final statement from the summit at Brdo Castle showed the US and EU were ready to threaten extra measures against Iran on top of UN sanctions if it keeps defying demands to suspend sensitive nuclear work.
The US and its European allies agree Iran should not be allowed to acquire nuclear weapons, although Tehran insists its nuclear program is strictly for civilian purposes.
But it remained unclear how far the Europeans, who rarely echo Mr Bush's harsh rhetoric against Iran and have sometimes been reluctant to get tougher, would be willing to go.
Washington has pressed the EU to deny some Iranian banks access to the world financial system.
EU diplomats have said recently the Union could go beyond already-approved sanctions, citing previous travel bans and asset freezes.
On climate change, George Bush has said a global agreement on fighting climate change could still be reached during his presidency, which ends early in 2009.
Mr Bush was speaking at a news conference after a summit with the 27-nation European Union's top officials in Slovenia.
The EU has often criticised the United States for having failed to ratify the Kyoto protocol on limiting greenhouse gas emissions blamed for climate warming or taking action to lower emissions of carbon dioxide.
Mr Bush will also travel to Germany, France, Italy, the Vatican and the UK.
He is expected to stop in Belfast on his return journey to the US next week, to meet the First Minister Peter Robinson and Deputy First Minister Martin McGuinness at Stormont.
