GUANGZHOU -- Police from China and Australia have captured five suspects in cross-border drug trafficking.

A total of 100 kilograms of methamphetamine was seized during raids in Shenzhen in January, police in South China's Guangdong province said Monday.

The police were tipped off in November 2016 that a gang of drug dealers was trafficking drugs from China to Australia.

Three Chinese (including two from Hong Kong), one Australian and one Fijian were seized in raids in February and March.

Police from the two countries signed a joint anti-drug operation deal in November 2015. Since the agreement, 150 drug dealers, 4,140 kilograms of various drugs and 3,310 kilograms of raw materials for drugs have been seized.
