Lobsang Sangay, a 43-year-old Harvard scholar, has been sworn in as head of the Tibetan government in exile, replacing the Dalai Lama as the movement's political leader.
The new prime minister, who has never set foot in Tibet, will assume the duties relinquished by the Dalai Lama in May.
The Dalai Lama will retain the role of spiritual leader.
The August 8 ceremony, presided over by the Dalai Lama, was held in the Tsuglagkhang Temple, the spiritual center of the Indian hill town of Dharamshala, where the government in exile is based.
Sangay vowed to follow the Dalai Lama's approach of seeking increased autonomy for Tibet within China, adding he was ready to negotiate with the Chinese government "anytime, anywhere."
Born and raised in the northeast Indian, Sangay went on to study at Delhi University before completing a master's degree at Harvard Law School.
He took up residency in United States and became a senior fellow at the school.
