China's top banking regulator has told banks to reform by tackling China's "zombie firms", control regional housing market bubbles and push forward with debt to equity swaps, according to a statement posted on the regulator's website late Friday.

Guo Shuqing, who was appointed chairman of China's banking regulator in February, met with representatives from a number of the country's largest commercial banks on Friday to check up on their progress implementing the central government's reform agenda.
