By Ben Blanchard BEIJING (Reuters) - China aims to stamp out the voice of exiled Tibetan spiritual leader the Dalai Lama in his restive and remote homeland by ensuring that his "propaganda" is not received by anyone on the internet, television or other means, a top official said. China has tried, with varying degrees of success, to prevent Tibetans listening to or watching programs broadcast from outside the country, or accessing any information about the Dalai Lama and the exiled government on the internet. The Dalai Lama's picture and his teachings are also smuggled into Tibet, at great personal risk. Writing in the ruling Communist Party's influential journal Qiushi, the latest issue of which was received by subscribers on Saturday, Tibet's party chief Chen Quanguo said that the government would ensure only its voice is heard.
