According to the news, what is the main reason for China’s rapid economic growth

China’s rapid economic growth in recent years has to a large extent been fuelled by business investment in new factories and other commercial premises, many of them producing low-cost manufactured goods.

A senior official in the Chinese central bank said they will, as he put it, "remove fuel from the fire", to reduce the risk. The idea is to constrain commercial banks’ lending. Banks that lend too much may be required to buy low interest financial assets, reducing the amount they have available to lend to businesses.
