China would like to strengthen intelligence sharing and joint law enforcement with other nations to combat drug offenses committed by foreigners, according to the Ministry of Public Security.

This includes China's plans to provide more technical support and help with personnel training for countries in the Golden Triangle, an area straddling Laos, Myanmar and Thailand, and the Golden Crescent, including Afghanistan, Iran and Pakistan.

The two areas are the world's two biggest production areas for heroin and methamphetamine, said a senior official in the ministry's Narcotics Control Bureau.
