Monks who support China's Communist leaders have been appointed to top positions in the monastery of the Panchen Lama, Tibetan Buddhism's second-highest leader, a monitoring group reported yesterday. They succeeded the moderate abbot removed on suspicion of passing information to the Dalai Lama, the exiled Tibetan god-king, the Tibet Information Network said. The change in leadership at the Tashilhunpo monastery was the result of a controversy between the Chinese government and the Dalai Lama over the reincarnation of the late Panchen Lama, the highest-ranking monk to remain in China after Chinese troops entered Tibet in 1959.
