GUANGZHOU, Jan. 12-- Police in south China's Guangdong Province said on Monday they have seized 172 kilograms of methamphetamine and caught 16 suspects who allegedly trafficked drugs to Indonesia.

Two primary suspects, surnamed Hu and Chen, and eight others were nabbed on Nov. 11, 2014 during a police raid, said a spokesman with the public security bureau of Guangzhou, capital city of Guangdong.

Police confiscated about 2 kilograms of methamphetamine, more than 1.9 million yuan (about 306,000 U.S. dollars) in drug money, and three vehicles used for drug trafficking, according to the spokesman.

Chen, from Hong Kong, confessed that he purchased more than 150 kilograms of methamphetamine from Hu and shipped it to Jakarta, Indonesia. The Jakarta police later caught several other suspects and seized the drugs on Nov. 22.

On Jan. 5, a joint operation by authorities in Guangdong, Hong Kong and Indonesia captured nine suspected drug traffickers in Indonesia and seized 862 kilograms of methamphetamine.
