(Yicai Global) June 25 -- China's transport ministry aims to expand its high-speed railway network by one-fifth to 30,000 kilometers by 2020, up from 25,000 km as of the turn of the year.

Authorities have drawn up plans related to the expansion with the goal of reaching 80 percent of China's cities with a population of at least one million people, state-backed news outlet The Paper reported.

The transport ministry also aims to increase China's expressways to 150,000 km, up from 136,000 km last year. The network will cover almost all cities with a population above 200,000 people. The government plans to add some 180 deep-water berths at coastal ports, and approximately 2,700 kilometers of waterways.

In terms of air transport, authorities aim for civilian airports to serve all cities with more than 200,000 people. There are also plans to establish higher-quality, interconnected transport infrastructure networks, linked to transit hubs.
