MOSCOW, March 31 (RIA Novosti) - Russian President Dmitry Medvedev will pay a one-day visit to Germany on Tuesday to meet with Chancellor Angela Merkel ahead of thiw week's G20 summit in London, a Kremlin source said.

The two leaders are expected to discuss Russian-EU relations, which have been disturbed by the fall of the government of the Czech Republic, which holds the European Union's rotating presidency, ahead of a biannual summit.

"A regular Russia-EU summit is scheduled for May," the source said. "The exchange of views with Germany as one of the engines of European integration becomes increasingly important in connection with the latest political turmoil in Czech Republic, which holds the EU presidency."

Russia earlier expressed hopes that the current political situation in the Czech Republic, where the government resigned after losing a vote of no confidence, will not affect the planned Russia-EU summit.

Medvedev and Merkel are also expected to address the idea of a new European security treaty to be drawn up at a pan-European conference, proposed by the Russian president last June.

The two leaders may also discuss the agreement on modernizing Ukraine's Soviet-era gas pipeline network signed by Ukraine and the EU last week. The document triggered an angry reaction from Russia, which exports most of its Europe-bound gas via Ukraine.

Economic and trade cooperation will also be on the agenda of the meeting.
