A gang was caught making crystal meth in a goat shed in southern China to cover up the smell made by producing the drug, according to a newspaper report.
Police seized more than two tonnes of partially made drugs at the illegal drug making factory in Guangzhou, the New Express reported.
Ten people were arrested earlier this month, including three of the main members of the gang from Taiwan, according to the article.
Police have been targeting the suspects since March when 100kg of crystal meth was found inside four air compressors that were to be shipped abroad.
Four other suspects were arrested in May and June.
The group, which had produced 2.79 tonnes of drugs at their three production sites, operated in five countries in Asia and the Asia-Pacific region, plus Taiwan, the report said.
Guangzhou has recorded 2,663 drug related cases this year, a seven per cent increase compared with the same period in 2015. Some 2,376 suspects were arrested, the newspaper reported.
China had more than two million drug users by the end of 2015 and over 60 per cent were aged 35 or under, according to a government report.
Crystal meth, also known as ice, is one of the most widely used illegal drugs in the country, according to the report.
