BEIJING, Aug. 14 (Xinhua) -- Chinese Vice Premier Li Keqiang has called for the deepening of cooperation with other developing countries, and achieving mutual benefits with the countries aided by China.

Li made these remarks during a recent visit to an exhibition that showcases the country's international aid effort in areas such as infrastructure, agriculture, medical treatment, industrial development, environmental protection, culture and education.

This year marks the 60th anniversary of the country's international aid.

"As a developing country, China, while devoted to its own development, has been providing aid as best as it could for other countries in economic difficulties," Li said.

He added that the policy must be continued and improved because there is an increasing imbalance in the economic development among different regions in the world.

"All aid workers have made noble contributions to our country's international aid cause, and some of them even sacrificed their lives. People will never forget them," Li said.

The exhibition on Aug. 12-16 in Beijing has been jointly held by 28 ministries and organizations, including the ministries of commerce, foreign affairs and finance.
