BEIJING, Jan. 23 -- Beijing closed or removed 392 polluting factories in 2014, according to the municipal people's congress, which opened on Friday.

A total of 30 industrial relief and cooperation platforms and 53 related programs were launched to pull the polluting companies out of Beijing in the past year, mayor of Beijing Wang Anshun said in a government work report.

An additional 36 low-end wholesale markets were also shutdown.

The municipal industrial and commercial authorities have turned down 3,760 applications for new businesses because they were on the list of prohibited or restricted operations.

According to the report, relocating non-core functions from Beijing has become a priority in the coordinated development of municipalities of Beijing and Tianjin and Hebei Province. Another 300 factories are expected to be closed in 2015.
