China's National Railway Administration should establish a working team to boost Premier Li Keqiang's efforts to help Chinese high-speed railway enterprises win projects abroad, a tunnel and rail expert said.

"China has rich expertise and experience in constructing and operating a large-scale high-speed rail network," said Wang Mengshu of the Chinese Academy of Engineering.

China is the only nation in the world that has carried out large and complicated railway projects over the past decade, and some of the projects are in harsh environments such as the high-altitude Qinghai-Tibet Plateau and in bitterly cold Northeast China, he said.
