A development plan for the country's medium and long-term urbanization will be launched in the second half of the year, an official with the country's top planning agency said on Thursday.

The main content of the plan will be a detailed layout of Premier Li Keqiang's concept of "new-type urbanization", focusing on giving the nation's 250 million migrant workers more recognition as urban residents, said Li Tie, director-general of the China Center for Urban Development at the National Development and Reform Commission.

According to Li Tie, the plan consists of four parts, with the first being "to orderly promote a sustainable urbanization process, which will focus on building smart, ecological and low-carbon cities".
