YINCHUAN -- Vice-Premier Li Keqiang on Wednesday said China will work with emerging-market economies and developing countries to inject vigor into world economic recovery.

Li made the remarks as he addressed the 2012 China (Ningxia) International Investment and Trade Fair and 3rd China-Arab States Economic and Trade Forum in Yinchuan, capital of Northwest China's Ningxia Hui autonomous region.

The vice premier noted that China has nearly doubled its trade volume with emerging-market economies and developing countries and nearly tripled its direct investments in the area over the past five years.

"China is willing to strengthen cooperation with those countries to help more nations join common development and achieve more sustainable prosperity," he vowed.

According to Li, China will strengthen strategic cooperation with emerging-market economies and developing countries to provide support on issues concerning each other's core interests, maintain close coordination in major international affairs and help build a new world political and economic order.

"China will also expand mutual-benefit cooperation and promote long-lasting cooperation with those countries to make full use of each other's economic advantages, extend the industrial chain and speed up cooperation among those countries," Li said.
