The China Securities Regulatory Commission issued four policy documents on March 15. The four documents showed the regulatory authorities' determination to strengthen capital market supervision, improve the quality of listed companies, optimize the construction of investment institutions, and strengthen their own construction.

The positive signal of continuing to deepen reforms is conducive to promoting China's capital market to further become mature, standardized and healthy, experts say. The documents were published by the China News Service, a state-run news agency in China, on the 15th and 16th.
