China is to launch a two-year campaign to fight corruption and misconduct in the construction sector, the Supreme People's Procuratorate (SPP) said Monday.

The move aimed to crack down on offences such as embezzlement, bribery and misconduct in the construction sector and improve the system to prevent offences.

Zhang Geng, SPP deputy procurator general, said the procuratorates nationwide had investigated 16,830 bribery cases in the sector from January 2006 to June 2009, accounting for 46 percent of all commercial bribery cases during that time.

The campaign will focus its efforts on offences such as corruption resulting in substandard construction and giving the green light to construction without a permit.
