The 200-meter tall China Telecom building in Changsha, the capital of the southern Hunan province, “burned with great intensity,” state broadcaster CCTV said.
Videos of the blaze shared online showed huge plumes of thick black smoke billowing into the sky as flames appeared to erupt from almost the entire height of the building.
State media said the fire was extinguished.
The Hunan fire department said no casualties had been found, Singaporean outlet CNA reported, adding that preliminary investigations suggested the outer wall of the 42-story tower had caught fire.
