China Banking Regulatory Commission and China Insurance Regulatory Commission detailed the rules for commercial banks' sales of insurance products in a joint press release on Thursday.

The rules encourage long-term insurance products, stipulating that premiums generated by health, life, credit and other long-term insurance products shall make up at least 20 percent of the total premium.

The headquarters and the primary branches of commercial banks must report their statistics of premiums for different types of insurances in the previous quarter to CBRC. Local banking bureaus must report their premiums within 10 days after the end of the quarter.

Commercial banks shall not make or design any promotional brochures or other materials to sell insurance. Each of the outlets for commercial banks shall not cooperate with more than three insurance providers within a fiscal year.
