A subway train the company developed for Turkey began trial operations in November. The train will run on a subway line linking downtown Istanbul to the city's airport, which will open next year. It will be the fastest subway line in Turkey, with a speed of 120 kilometers per hour.

"The Chinese rail transit equipment manufacturing industry is one of the industries with the highest-level innovation and strongest international competitiveness," said Feng Yaoxiang, an official from the China Council for the Promotion of International Trade.

"The industry is a core competitive advantage of China's high-end equipment manufacturing in the global market," Feng said.

After more than 60 years of efforts, China has built an advanced rail transit equipment manufacturing system featuring independent research and development, complete supporting facilities, and large-scale operations.

The country ranks first in railway electrification and operating mileage of high-speed and urban railways, according to Feng.
