China has built over 16,000 kms of high-speed train tracks connecting most of the major cities.
The two trains - "Golden Phoenix" and "Dolphin Blue" - travelling at 420 km per hour crossed on lines between Zhengzhou in the central Henan Province and Xuzhou in the eastern Jiangsu Province.
The experiment set a world-first for trains travelling at such speed, Zhou Li, head of the technological management department of China Railway Corporation, told state-run Xinhua news agency.
Zhou said the achievement, using homegrown trains, demonstrated that China has fully mastered the core technology of high-speed trains.
