The U.S. Statement Department's annual report on Human Rights was released on Saturday by Secretary of State John Kerry, which reported severe repression and marked deterioration of human rights in Tibet.
The annual report on human rights in Tibet says the Chinese government's respect for and protection of human rights in the TAR and other Tibetan areas deteriorated markedly.
"Under the banner of maintaining social stability, the government engaged in the severe repression of Tibet's unique religious, cultural, and linguistic heritage by, among other means, strictly curtailing the civil rights of China's ethnic Tibetan population, including the freedoms of speech, religion, association, and movement," said the report.
"There was a deepening perception among Tibetans that they were systemically targeted for economic marginalization and educational and employment discrimination," the report notes.
It documents other serious human rights abuses like extrajudicial killings, torture, arbitrary arrests, extrajudicial detentions, and house arrests.
The report says there was a high level of security forces throughout Tibet, particularly at major monasteries.
The oppressive security measures by authorities during its leadership transition across the Tibetan Plateau contributed to a further deterioration of the human rights situation, it added.
