European Union Commission President Jose Manuel Barroso is expected in Moscow Thursday to prepare for next month's summit between Russian President Vladimir Putin and EU leaders.

The EU Commission says Mr. Barroso's talks with President Putin aim at finding ways to improve cooperation with Russia.

The summit, on May 10, will take place one day after ceremonies in Moscow commemorating the 60th anniversary of the end of World War II in Europe.

The two sides are trying to create four major areas of cooperation: the economy; freedom, security and justice; external security; and research, education and culture.

However, officials say there remain areas of disagreement, including on the introduction of a more liberal visa policy between the EU and Russia.
