All but two of the EU's 27 leaders have signed a new treaty to enforce budget discipline within the bloc.
The "fiscal compact" aims to prevent the 17 eurozone countries again running up huge debts.
In a speech at the signing ceremony, President of the European Council, Herman Van Rompuy, said: "The restoration of confidence in the future of the eurozone will lead to economic growth and jobs."
