China's top economic planning agency has revised its policy guidelines to encourage more foreign investment into the industrial upgrade of the country's central and western regions.

The new guidelines, which will become effective on June 10, include details of favorable policies and incentives being offered in mostly labor-intensive industries and service sectors, according to a statement from the National Development and Reform Commission.

The policies are aimed at exploiting the economic benefits of the unique natural resources and environmental advantages of the regions, the statement said.
