Kandahar is the birthplace of the Taliban movement and a major producer of poppies（罂粟yīng sù） - a key ingredient in opium and heroin. During the past two years, the province has seen fierce fighting between insurgents and U.S., NATO and Afghan forces

One of China's top drug-fighting officials, Yang Fengrui, says he is concerned more foreigners in China during the Olympics could mean more illegal narcotics（致幻毒品）.

"In order to ensure the security of the Olympic games, and to host a green Olympic games and a drug-free Olympic games, （为了办一届“平安奥运、绿色奥运”，也可以说是“无毒奥运”，）the central government has instructed the law enforcement departments to do a lot about drug control during the Olympic games, in order to curb the inflow of drugs from overseas," said Yang.

Yang wears two hats. He is the director general of the Ministry of Public Security's Narcotics Control Bureau. He is also the permanent deputy secretary general of the newly-created China National Narcotics Control Commission, an agency created by a law that went into effect June 1.

The Chinese official says another issue of concern is the effort to smuggle heroin through China. He says the heroin supply out of southeast Asia's Golden Triangle region -- made up of Burma, Laos and Thailand -- has decreased significantly. At the same time, he points to a relatively new area of opium production, the so-called Golden Crescent（金新月），an area that straddles（跨越） Afghanistan, Pakistan and Iran.

Chinese authorities recently foiled（挫败） one case involving 50 kilograms of heroin and 30 carpets imported from Afghanistan and Pakistan. Officials say smugglers had injected the heroin into flexible plastic tubes, one to two millimeters（毫米） in diameter, and then wrapped the tubes into colorful fibers that were woven into the carpets. 

Yang says the Chinese government has taken special measures to deal with the threat of drugs from Afghanistan, which produces more than 90 percent of the world's supply of opium.

"First, at the border areas and related high-risk areas, we have strengthened efforts to block the drug sources," Yang said. "And, we have also established checkpoints and inspection stations on the road routes, land routes, sea routes and air routes, and also mail routes, to maximize our ability to inspect and block drug sources."

在边境地区和有关地区采取堵源截流的措施，陆路、海路、空路、邮路，建立查缉体系，最大限度地查缉堵截毒品入境。

Yang acknowledges there has been what he describes as a "very little amount" of opium poppy cultivation in China, in eastern Fujian Province, in western Gansu Province and in northeastern Heilongjiang Province. He says Chinese authorities use satellite pictures to detect the illegal crop and have been able to take immediate action to eradicate the problem.

Yang also says a small number of Chinese families in what he describes as "the border areas of cities," also grow opium poppies, but he says it is only because they enjoy the beautiful flowers.
