CHANGCHUN, Aug. 23 (Xinhua) -- The 12th China-Northeast Asia Expo and the 10th High-level Forum on Northeast Asia Cooperation opened Friday in Changchun, capital city of northeast China's Jilin Province.

Vice Premier Hu Chunhua attended the opening ceremony and read the congratulatory letter of Chinese President Xi Jinping.

Hu, also a member of the Political Bureau of the Communist Party of China (CPC) Central Committee, said that the letter highly affirmed the development vitality of Northeast Asia, and pointed out major Belt and Road opportunities for expanding and deepening regional cooperation.

Northeast Asia is one of the most dynamic and potential regions in Asia and even in the world, which brings favorable conditions and rare opportunities for strengthening regional cooperation, Hu said.

China is ready to work with other Northeast Asian countries to further expand trade and investment, deepen industrial chain cooperation, and raise the level of infrastructural connectivity, he said.

"A more open and prosperous China will surely create more business opportunities for enterprises in northeast Asia and the world at large. We expect more cooperation to be achieved at the expo, which is a platform for in-depth communication and exchanges," he said.
