China plans to enhance its monitoring network for drug related crimes with the country's first anti-drug bill which was introduced in its legislature on Tuesday.

The bill sets strict rules over the clinical use of narcotics and other chemicals and medicines that could be used to make illegal drugs.

Regular checks will be required during the production, sale and use of sensitive clinical medicines. The bill stipulates that farms that grow medicines and warehouses that store them will be under state guard.

The bill also requires owners and managers of discos, bars, and night clubs, to post anti-drug signs in prominent places inside the venues and to report drug takers to the police.

The bill will also authorize police to search people and their luggage for illegal drugs at key public places such as train stations, long-distance bus stations and border crossings.

"It is important to introduce such a law as China is now facing a grave situation in drug control," said Zhang Xinfeng, vice minister of public security, in a brief to lawmakers of the Standing Committee of National People's Congress.

China is experiencing an increase in drug trafficking flowing from the Golden Triangle, an area located in countries along the Mekong Rive delta including Myanmar and Laos, and the Golden Crescent area in western Asia.

Zhang said drugs from the Golden Triangle are "pouring" into China, posing a great threat to China's drug control efforts.

Police estimate that China has more than 700,000 heroin addicts, 69 percent of whom are under the age of 35.

"It's impossible to fight the drug problems without international cooperation," Zhang said, noting the bill stipulated that Chinese police should share information with other countries and international organizations and enhance collaboration in investigations.

The bill requires Chinese authorities to share the seizures and the revenues from drug crimes with other countries and regions in operations outside its border.

And Chinese authorities would be required by the law to support and assist in other countries' opium replacement crop planting.

China has already launched opium replacement planting schemes with Myanmar and Laos and other neighboring countries. Rubber, tea and other crops were grown as substitutes.

Earlier this year, China and Myanmar confirmed after investigation that the Wa State of Myanmar has realized its goal of banning poppy production.

Observers said the new law showed more humanitarian concern for drug users as the law would allow many of them to recover in their communities, rather than being confined to rehabilitation centers as the current drug control regulation requires.

The bill stipulates that rehabilitation centers would only admit frequent intravenous drug takers, people who refuse community assistance, or fail in community corrections, and those who live in communities without correction resources.

Rehabilitation centers should be classified to serve people of different ages, gender, and addictive conditions, with abuse and humiliation strictly banned.

It also bans discrimination against people who are under or through rehabilitations in terms of education, employment, and social security benefits.
