Sources with the Chinese Ministry of Public Security said that police from southwest China's Yunnan province and their counterparts in Myanmar have smashed a drug-making plant in Myanmar's Laogai and captured 347 kg of methamphetamine, or ice, and 120 kg of tramadol in the operation.

In May, Yunnan's anti-drug police authority uncovered an important clue alerting them that a male suspect named Mu Ronghong was leading other suspects in Myanmar to produce, smuggle and sell drugs.

After a two-month investigation, Chinese and Myanmar police captured 10 suspects in Laogai after raiding the drug plant on July 9.

At the same time, Chinese police successfully captured Mu Ronghong in Yunnan's Lincang city.

According to the ministry, police on the Chinese mainland have cracked 11 drug-related cases in cooperation with counterparts in Myanmar, Vietnam, the Philippines, Hong Kong and Taiwan since the beginning of 2012.
