Senior Party and government officials from 22 provinces, municipalities and autonomous regions have returned government cars and left houses that were illegally occupied after the central government sent special inspection groups to visit local governments in a national anti-graft campaign earlier this year, Xinhua News Agency reported.

But the report did not reveal how many government vehicles and houses had been returned.

Many provincial, city and county governments have suspended construction of unnecessary office buildings and other property projects, the report said.

Meanwhile many local governments have also canceled unnecessary overseas visits and tours to save public funds.

The country's top anti-graft agency pledged to take concrete and effective measures to prevent and fight corruption and investigate both "flies" and "tigers", or low ranking officials and senior officials.
