Top Chinese advisers have warned that although rapid urbanization contributes significantly to the country's economic growth, it can also cause major "growing pains."

China has entered a period of rapid urbanization, with experts predicting that 1.12 billion people - or 70 percent of the total population - will live in cities by 2050. More than 600 million Chinese people will shift from rural to urban areas in the next 50 years.

By then, China will have 50 major cities, each with a population of more than 2 million, 150 large cities, 500 medium-sized cities and 1,500 small ones.
