KUNMING, June 17 (Xinhua) -- Police in southwest China's Yunnan Province have captured one suspect for drug trafficking and seized 26.2 kg of methamphetamine, local authorities said on the weekend.

On June 2, police in the border city of Pu'er captured the driver of an off-road vehicle during a public inspection and found 140 packages of the drug from the modified doors on both sides of the vehicle.

Further investigation is underway.

Since the beginning of this year, local authorities in Pu'er have set up a 24-hour drug inspection network on the city's main traffic trunks, which has effectively curbed the inbound trafficking of drugs and prevented the smuggling of drug-making materials out of China.

Yunnan is a major front in China's battle against drug crime, as it borders the Golden Triangle known for its rampant drug production and trafficking.
