BEIJING, Jan. 5 (Xinhua) -- Beijing's subsidiary administrative center aims to build seven major industrial clusters by 2025.

Sitting in Tongzhou District, east of the capital, the sub-center aims to build seven industrial clusters each worth several hundred billion yuan, officials said at the ongoing legislative and political advisory sessions of Tongzhou District.

The industrial clusters will involve headquarters economy, finance management, cultural tourism, culture and technology development, cutting-edge chip-making, IT software building and intelligent manufacturing.

Currently, the district is stepping up construction on business, cultural tourism, and technology and innovation parks.

Beijing is shifting some of its administrative functions out of the city center into Tongzhou to help address problems including traffic congestion and air pollution.
