European Union leaders were locked in intense talks on the second day of a summit on Friday seeking to break a deadlock with Britain and Poland over a new reform treaty.
German Chancellor and EU president Angela Merkel met with British Prime Minister Tony Blair in an effort to ease concerns about his country's objections.
"We will exchange our views and assessments of the situation. We shall also work on the text. I can't tell you more for the moment, only that we shall continue to work hard," Merkel said.
The EU is looking for a way to simplify decision-making after the collapse of its proposed constitution which was rejected by French and Dutch voters in 2005.
After months of negotiations, the Germany presidency, which runs until the end of next week, distributed a new draft text of its "reform treaty" to its EU partners for the first time on Tuesday.
The treaty is meant to simplify the way the 27-member bloc makes decisions as it expands, establish a "foreign minister" and installs a longer-term president to replace the cumbersome rotating system in place now.
