"The purchase price fell to 140 yuan ($22) from 150 yuan per 50 kilograms" a few months ago, said Liu Yinmei, a farmer in Liyang city of Jiangsu province, cited by Xinhua News Agency.
"I will not sell at such a price. I shall wait for it to go up a bit," she added.
Meanwhile, as large companies scrambled for imported rice, smaller processing mills were at a competitive disadvantage from higher production costs and lower selling price, companies and analysts said.
Xu Weidong, manager of a processing company in Liyang, said: "Our business has been hurt by (rice imports) as the price of processed rice also declined."
