Chinese authorities are drawing up new land support policies for western parts of the country, following a sharp spike in land abuse cases in the region during the first three months of the year.

In the first quarter, cases jumped 22.4 percent year-on-year, according to statistics released by the Ministry of Land and Resources on Friday.

"Due to the focus on development of the western regions, demand for land from infrastructure construction and investment is increasing sharply, putting pressure on land supply," said Yue Xiaowu, deputy director of the ministry's law enforcement and supervision administration.
