Chinese state media say Tibet's governor has tendered his resignation and will step down this week.
The report, by the official Xinhua news agency, did not give a reason for the resignation nor say who would replace him.
Jampa Phuntsok, an ethnic Tibetan, was governor during demonstrations by Tibetans in their capital of Lhasa that turned deadly on March 14 of 2008.
Tibetan People's Congress Chairman Legchok is also to resign. Both men are said to be in their early-to-mid sixties, near standard retirement age.
The resignations are not expected to have an effect on Chinese government policy toward Tibet, which is determined primarily by the central government under president Hu Jintao.
China's approach to Tibet includes investment in the region's economy while countering strong support for the Dalai Lama, the region's Buddhist leader, who fled into exile in India in 1959 following a failed uprising against Chinese rule.
