German Chancellor Angela Merkel and French President Nicolas Sarkozy began a one-day summit on Monday to seek compromises on key issues ahead of France's EU presidency.

Energy and global warming are high on the agenda of the summit at the southern German town of Straubing, which also involved French Prime Minister Francois Fillon and the two countries' foreign, defense, economy and environment ministers.

In an interview with the German daily Straubinger Tagblatt published on Monday, Merkel said Sarkozy could count on Germany's full support during France's six-month EU presidency which begins on July 1.

One of the thorny issues which have put Germany and France at odds is France's plan to push through binding rules for EU states to implement ambitious greenhouse gas emission targets for cars.
