Energy cooperation and infrastructure construction will be new engines for cooperation among China and Eurasian countries, driven by China's Silk Road economic belt initiative, said experts.

President Xi Jinping last year proposed that China and Central Asia join to build a Silk Road economic belt. Some 4 billion people live along the path of the new trade route.

"I think it would be a win-win solution, China can diversify its energy supply channels while the economies of these countries can be boosted by new projects," said Zhao Hongtu, a research professor at the China Institutes of Contemporary International Relations, a government think tank.
