European Central Bank President Jean-Claude Trichet unexpectedly joined French President Nicolas Sarkozy and German Chancellor Angela Merkel for talks late Wednesday in Berlin, in an attempt to resolve the Greek debt crisis, dpa reported.
The late-night meeting took place ahead of a eurozone summit planned for Thursday in Brussels.
There was hope that the leaders might be able to agree on a series of measures to shore up the Greek economy, according to German government sources.
All three leaders are expected in Brussels a meeting of the heads of state of the 17 eurozone members, aimed at resolving Greece's ongoing debt crisis and restoring market confidence in the euro.
If France and Germany are able to agree, it is thought that a breakthrough will be possible in Brussels. The two countries differ over the role of private investors in a second Greek bailout package.
