GUANGZHOU -- Police confiscated 10.4 tonnes of drugs during the first 10 months of this year in South China's Guangdong province, a region plagued with rampant drug production and trafficking.

They solved 13,000 drug-related cases and detained more than 16,000 suspects during that period, Zhai Kaixia, head of the provincial drug control bureau, said at a press conference.

In a typical case solved in July, police busted a drug production and sales ring, seizing more than 60 kilograms of methamphetamine as well as guns and bullets.

In an ongoing crackdown on cross-border drug trafficking, they intercepted more than 20 kilograms of heroin from Vietnam in July, with assistance from police in neighboring Guangxi Zhuang autonomous region.

The same month, they also captured 14 suspects, mainly Taiwanese, and seized more than 250 kilograms of meth. A delivery driver in the provincial capital Guangzhou received a reward of 300,000 yuan ($45,493) at the press conference for providing key information about the case.

Police have continued to fight drug-related crime in Lufeng city and Huilai county, two notorious meth production bases.
