The drought has caused water shortages for 4.6 million people and 4.1 million head of livestock, the Xinhua News Agency said, citing an announcement by the national anti-drought administration.
Affected areas stretch from Jilin province in the northeast to the grasslands of Inner Mongolia in the north and the drought is spreading, Xinhua said, citing an administration official, Zhang Xu.
Crops on some 22 million acres (8.7 million hectares) of farmland have been damaged, the report said.
The drought agency also warned of possible water shortages in Hunan and Hubei provinces in the south because of low rainfall and high temperatures, Xinhua said.
