The Chinese city of Qingdao has approved a CNY29bn ($4.2bn) plan to construct a 54.7km subway line network across the city before 2016.

The network forms Phase I and II of the city’s bigger plan to build a 231.5km network of eight subway lines in its downtown and suburban districts in the future.

Overall, China is planning to spend CNY200bn ($29.4bn) to build a 1,500km network of subways and light track lines by 2010 under its 11th five-year plan (2006–2010).

A further 1,700km rail network for 65 lines is planned for between 2010 and 2015.
