China, ASEAN can build 'diamond decade': Premier Li

China and member countries of the Association of Southeast Asian Nations (ASEAN) have the ability to build a "diamond decade," Chinese Premier Li Keqiang said at the opening ceremony of the tenth China-ASEAN Expo.

The past ten years have witnessed a golden decade of China-ASEAN cooperation, with bilateral trade volume increasing fivefold and the scale of cross-investment expanding threefold, Li said while giving a keynote speech.

China and ASEAN member countries have similar goals and development tasks, and it will unleash great energy by promoting China-ASEAN economic cooperation, the premier said.

The expo opened Tuesday in Nanning, capital of south China's Guangxi Zhuang Autonomous Region.
