Freer foreign capital flow vital for integration of A shares into global index

The ceiling for QFII investment is $80 billion, expanded in April 2012 from $10 billion, when the scheme was launched in 2002.

Meanwhile, the approved RQFII quota was 70 billion yuan at the end of March.

The CSRC has added a further 200 billion yuan to the quota since November 2012, and there are plans to further expand the investment pool.

There have also been rumors in the market suggesting that the securities watchdog may start approvals of new RQFIIs this week.

The CSRC said it would welcome the injection of more long-term funds from overseas.

"It would be helpful to improve the investment structure and quality of the A-share market, and the influence would be significant," an official from the commission said.
