MOSCOW, October 10 (RIA Novosti) - China has cautioned U.S. legislators against intervening in China's domestic affairs, specifically in Tibet, Xinhua reported.

The Tibetan spiritual leader, the Dalai Lama, on Tuesday received a U.S. Congress award in honor of the late U.S. human rights activist Tom Lantos.

"Tremendous progress has taken place in Tibet's social and economic aspects since its democratic reform and the human rights situation there is the best in history," Chinese Foreign Ministry spokesman Ma Zhaoxu said on Friday.

China accuses the Tibetan spiritual leader of separatism, advocating Tibetan independence from China.

Ma described the Dalai Lama as "a primary chief of the feudal serfdom in old Tibet, who is still running programs to divide the homeland and sabotage social stability and unity among nations in Tibet."
