More financial channels in the Chinese mainland are being opened for foreign investors, in a move to better support stable economic growth.

The China Securities Regulatory Commission agreed at the weekend to further lower the requirements for market access for qualified foreign institutional investors. The move is based on the stance of "deregulation with strengthened supervision".

The regulator encouraged long-term investment capital, including foreign pension funds, to be injected into the domestic market by choosing multiple trade brokers.

Investors with QFII quotas can also invest in the inter-bank bond market, as well as in privately raised corporate bonds for small and medium-sized enterprises, the CSRC said.

Overseas fund providers can hold 30 percent of the stocks of one company, compared with 20 percent before, which is a signal of an advanced opening-up reform to roll up the domestic capital market in the future, said a statement from the commission.

On July 20, the State Administration of Foreign Exchange approved a QFII quota of $1.2 billion for six new foreign institutional investors.

At the end of last week, 149 foreign institutions had received QFII approval in the mainland with a total quota of $28.53 billion, data from SAFE showed.
