BEIJING — A Tibetan man in China’s western Sichuan Province died on Saturday after setting himself on fire to protest Chinese policies in the region, according to Tibetan exile groups and Radio Free Asia, a news service financed by the United States government.

The man, Shichung, was the first person to carry out a self-immolation protest in Tibetan areas in more than two months and the 122nd person to do so since the gruesome campaign of suicides began in 2009.

Shichung, 41, who like many Tibetans uses only one name, was from Aba, a heavily Tibetan county that has been the scene of several self-immolations and antigovernment protests. The authorities have responded to the unrest by flooding the area with paramilitary police officers and closely monitoring Buddhist monasteries.

A few days before his death, Shichung had complained to friends about such heavy-handed policies, saying, “It seems they won’t leave us in peace,” the group Free Tibet reported, citing local sources.
