Police in Xishuangbanna Dai Autonomous Prefecture in southwest China's Yunnan Province have busted 39 major cross-border drug-trafficking cases and seized a total of four tonnes of drugs over the past five years.
Local police cracked 14 cross-border drug-trafficking rings and arrested 127 drug dealers, the public security bureau of the prefecture announced on Friday.
Xishuangbanna police have established good relationship with parties, governments and armed forces from neighboring countries, which contributed to the achievements.
Xishuangbanna, located in the south of Yunnan, is one of the Chinese border regions most affected by drug use, due to its proximity to the opium-growing Golden Triangle in Southeast Asia.
