BEIJING - China's railway investment maintained generally stable in the first eight months of this year, according to official data.

Fixed-asset investment in railways totaled 449.6 billion yuan ($63.6 billion) in the January-August period, basically equal to the same period of last year, said Meng Wei, spokesperson of the National Development and Reform Commission.

China will steadily advance the construction of ongoing projects and start to construct a batch of new projects to fulfill the annual investment target, according to Meng.

A new high-speed railway linking Southwest China's Chongqing Municipality and Kunming, capital city of Yunnan province, has been approved this month, involving a total investment of 141.6 billion yuan.

China plans to expand infrastructure investment in 2019, including 800 billion yuan in railway construction, according to a government work report.
