China may raise the upward limit for insurers looking to invest their assets into A shares to 20 percent from 10 percent now, the Shanghai Securities News reported on Friday.

The paper, quoting a source, said that the new guidelines may be released in August.

It was also reported on Thursday that China might ease rules on how much insurers can invest in infrastructure bonds.

Under a proposal being considered by the China Insurance Regulatory Commission, insurers would be permitted to have 10 percent of their assets in infrastructure debt, the China Securities Journal reported citing an unidentified source.
