China to spend $115 billion on railways in 2017: Chinese media

China plans to spend 800 billion yuan ($115.09 billion) on building railways this year, the same budget as last year, to grow its network to 150,000 kilometres, state news agency Xinhua reported on Wednesday.

China plans to add 2,100 kilometres of track this year, mostly in its central and western regions, and electrify 4,000 kilometres of railways, Xinhua reported, citing a statement released by national operator China Railway Corporation after an annual work conference.

The country, which had set an annual spending target of 800 billion yuan for the last three years, used 801.5 billion yuan on railway construction in 2016, according to local media reports citing the national operator. It plans to spend 3.5 trillion yuan on building railway tracks over 2016-2020, Xinhua said.

Railway spending was at a high of 840 billion yuan in 2010 before a high-speed rail crash that led to the arrest of numerous officials on corruption charges and the breakup of the railway ministry.

In recent months, the government sped up approvals of construction projects including railways to support slowing economic growth, adding to China Railway's debt burden which stood at 4.21 trillion yuan at the end of June.
