Chinese and Russian police have cracked a cross-border drug ring and seized about 935 kg of ephedrine in northeast China's Heilongjiang Province, local police announced Wednesday.

Police seized 13 suspects from a ring headed by Guo Changhai and their weaponry.

The ring allegedly started trafficking drug from China to Russia in 2002 and allegedly has dealt with about two tons of ephedrine, raw materials to make "ice" drug, according to Wang Xiaoxi, spokesman of Heilongjiang Provincial Public Security Department.

At Heilongjiang's 17 ports opening to Russia, drug trafficking crimes have been increasing along with the booming economic activities.

Russian and Chinese police have cooperated in cracking about 160 drug crimes over the past years, involving 110-plus suspects and two tons of drugs, according to local police.
