When Premier Li Keqiang highlights the safety and reliability of China's high-speed railway technologies at various forums, he knows that the rich experience gained from building huge rail networks would stand testimony to the nation's growing prowess in the sector, say industry sources.

China has already built the largest high-speed rail network in the world, and leads especially in making high-speed trains and the necessary infrastructure to support it. Currently, most of the rail makers are focusing more on enhancing innovation with a view to develop "China-designed" high-speed trains and to transfer technology to overseas countries.

"The nation has the most advanced high-speed rail technology and is looking for a chance to prove its credentials," says Guo Lei, a senior analyst for SWS Research Co, a unit of Shenyin & Wanguo Securities Co.
