British Foreign Office Minister Ivan Lewis is visiting Tibet this week for talks with regional leaders as part of a larger trip to China.
Lewis will visit the Tibetan capital, Lhasa, as well as the Chinese capital, Beijing, between Monday and Thursday.
The Foreign Office says Lewis will be exploring the political, economic, social and cultural situation of Tibetans.
The human rights group Free Tibet is urging the British minister to raise concerns about the treatment of Tibetans in his talks with Chinese officials.
The group says Chinese authorities are using widespread torture as a weapon to instill fear and self-censorship in Tibet. It also accuses China of denying Tibetan detainees fundamental rights and legal safeguards guaranteed in Chinese law.
Free Tibet criticized the British government's policy of "constructive engagement" with China, saying the approach has failed to deliver progress on human rights.
The group says the rights situation in Tibet has deteriorated drastically since last year, when Tibetans took to the streets to protest Chinese rule. Rights groups says 1,000 Tibetans are still missing after a violent crackdown by Chinese authorities.
