The China Insurance Regulatory Commission called for an end to haze-related products from the country's two biggest insurers, a week after they were introduced to the market.

PICC Property and Casualty Co Ltd began to sell haze-related insurance on March 17; the first batch was available only in Beijing with a limited number of 3,000 policies.

A day later, Ping An Insurance (Group) Co of China Ltd announced the introduction of similar products, covering seven cities, including Beijing, Shanghai and Guangzhou.
