China had put 2,595 high-speed trains into operation by the end of 2016, accounting for 60 percent of global high-speed trains.

"China Railway High-speed (CRH) trains have become a calling card for China," Wang Jun, deputy president of Chinese locomotive manufacturer CRRC, said at the first World Intelligence Congress which opened Thursday.

By the end of 2016, China had put 21 CRH model trains into operation. It had surpassed 20,000 kilometers of high-speed rail lines, with a target of adding another 10,000 kilometers by 2020 and surpassing 45,000 kilometers by 2030.

High-speed trains on the 1,318-kilometer Beijing-Shanghai route have carried more than 600 million passengers since the line was launched in June 2011.

CRH trains have been exported to 102 countries and regions, with agreements worth 18 billion U.S. dollars signed in 2016, an increase of 40 percent year on year.
