HNOM PENH, July 24 (Reuter) Cambodia's government said on Thursday it was taking strong measures against the illegal drugs trade, and rejected a U.S. newspaper report alleging links between the trade and government leaders. ``The Royal Government of Cambodia has taken strong and firm measures to crack down on drug trafficking, as a result we arrested many drug traffickers,'' Secretary of State for Information Khieu Kanharith said in a letter to the Washington Post. Copies of the letter were distributed by the information ministry. The letter was in response to a report in the newspaper that cited Western antinarcotics officials and Cambodian sources as saying Second Prime Minister Hun Sen had surrounded himself with suspected drug traffickers who bankrolled his projects, gave him gifts and sought to turn Cambodia into a ``narcostate.'' U.S. State Department Spokesman Nicholas Burns said the United States had no evidence linking Hun Sen to drug trafficking. But Burns said the United States had reliable reports that the president of the Phnom Penh Chamber of Commerce and prominent Hun Sen supporter, Theng Bunma, was a drug trafficker and would probably be excluded from the United States. ``We think the Cambodian government can do a lot more to purge itself of obvious corruption in the government, of obvious linkages between the government itself, members of government, and narcotraffickers,'' Burns said earlier this week. Khieu Kanharith said Theng Bunma had contributed money to government projects and won a bid to supply rice to the armed forces, but had never paid salaries for government troops. Cambodia's drug trafficking problems were highlighted last year when police and customs in Europe, Africa and Australia seized almost 60 tonnes of marijuana in containers that came from Cambodia. International antinarcotics officials say heroin from Burma is smuggled through Cambodia to the world market. Last year, the U.S. placed Cambodia on its list of leading drug trafficking nations. 08:04 072497
