China-Europe 2020 plan 'unprecedented': Premier Li (2)

They will work more closely on transportation and infrastructure, cooperate on science and technological innovation, while developing new energy sources and materials together.

The two sides will give full play to their high-level cultural communication and dialogue mechanism to expand exchanges in areas including education, culture, youth and public policy.

They also vowed to strengthen cooperation on international and regional issues, such as the climate change, internet security, arms control and nonproliferation.

In China-Europe relations, common ground outweighs differences, Li said, attributing those differences to their histories, cultures and development stages.

"Any problem in China-Europe relations can be resolved as long as we increase communication and enhance understanding," Li said.

He said China and Europe strengthening cooperation is in both sides' interests, and will send positive signals of peace, development and cooperation to the world.

China firmly supports Europe's integration, and is glad to see a strong, prosperous and united EU.

The combinations of two cultures and two markets will lift China-Europe relations to a new high, Li added.

Stressing that the two economies had become interdependent and trade volume had quadrupled, Barroso said Europe-China relations are not only represented by trade, but also by politics, security and culture.

Barroso said Europe and China are now at a turning point, citing Europe's own market reform and China's situation after the recent Communist Party of China plenum.

Barroso said Europe supports the Chinese economy to be more inclusive and sustainable.

Following the summit, Li, Rompuy and Barroso witnessed the signing of three deals on energy, intellectual property rights and agri-technology.
