KUNMING - Police in Southwest China's Yunnan province have caught three suspects and seized 174.19 kilograms of methamphetamine, local public security department said Monday.

Earlier this month, police in Menglian county received a tip-off that a group of drug dealers were planning to bring a large amount of drugs over the border to China.

The gang was busted on April 14 in Lancang county, police said.

The case is under further investigation.

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