BEIJING — Less than a month after it was seized by the Chinese government, Anbang Insurance Group, the giant conglomerate, is once again offering small investors “you snooze, you lose” investment opportunities — your money back, guaranteed.

Sold like stocks or bonds in bank branches around China, the products carry names like Anbang Abundant Stability No. 10, suggesting the investments are conservative. They are anything but.

In the past, Anbang has used the money it raised from those products to help pay for risky deals like the purchase of the Waldorf Astoria hotel in New York and other flashy properties around the world. The approach saddled the company with big debts at a time when the authorities were trying to stamp out financial troubles.

Still, Anbang and other companies keep selling them — and Chinese investors keep buying them. When China took over Anbang, it only underlined the widely held — and potentially dangerous — belief that the Chinese government will always be there to bail them out.
