President Xi Jinping has visited the politically troubled region of Tibet, the first official visit by a Chinese leader in 30 years.
The president was in Tibet from Wednesday to Friday, but the visit only reported by state media on Friday due to the sensitivities of the trip.
China is accused of suppressing cultural and religious freedom in the remote and mainly Buddhist region.
The government denies the accusations.
In footage released by state broadcaster CCTV, Mr Xi was seen greeting a crowd wearing ethnic costumes and waving the Chinese flag as he left his plane.
He arrived in Nyingchi, in the south-east of the country and visited a number of locations to learn about urban development, before travelling to the capital Lhasa on the high-altitude railway.
