More than170 people are reportedly dead or missing, while over 2 million have been affected by deadly floods, the worst since 1955, in eastern China.
With torrential rains continuing in Zhejiang and Hubei provinces, there are growing fears that casualties of the flood will increase as most parts of the country are reportedly under water.
The government has mobilised troops to evacuate hundreds of thousands of people.
Reports say nearly 1,000 businesses were being disrupted and crops destroyed, pushing up food prices.
Downpours earlier this week triggered landslides that buried houses and killed dozens of people mostly in Zhejiang and Hubei.
The floods come after months of crop-destroying drought in the centre and north of the country.
Analysts say crop shortages in China could affect prices around the world.
