About 250 tonnes of illegal explosives will also be disposed off in the next few days, China's Ministry of Public Security said in a statement today.
A large portion of these guns, destroyed yesterday, were seized by police during raids, and others were submitted by citizens, the statement said.
Half of the guns were confiscated during a national campaign targeting illegal guns and explosives, which started in February and will last until December, it said.
So far, police have busted more than 180 criminal organisations and detained 7,800 suspects involved in the illegal possession of guns and explosives, the statement said.
Since January, the number of criminal cases involving guns has dropped by 9.7 per cent from the same period of last year, and criminal cases involving explosives have fallen by 21.6 per cent, the statement said.
