BRUSSELS - Top leaders of the European Union (EU) have called on Europe's politicians to take joint action and ensure the bloc plays "a key role" in making next month's G20 summit in Seoul a success.

A letter from European Council President Herman Van Rompuy and European Commission President Jos Manuel Barroso made public on Friday said: "The G20 Summit in Seoul comes at a critical time. It will be a real test of whether the G20 can continue to deliver in its role as the premier global forum for international economic cooperation."

On the occasion of the EU summit on Thursday and Friday, they proposed that world leaders should drive forward the global recovery by forcefully implementing the G20 framework for strong, balanced and sustainable growth.
