China's richest man, real estate magnate Wang Jianlin, has warned the country's property market is the "biggest bubble in history" -- the latest alarm bell to be sounded on the faltering giant economy. Wang, the owner of real estate and entertainment conglomerate Wanda, said property prices continue to rise in the country's big metropolises but fall in smaller cities, which are saddled with huge inventories of unsold new homes. "I don't see a good solution to this problem," Wang, whose group owns more than 200 malls, shopping complexes and luxury hotels across China, told CNN in comments published on its website.

Clinton is hoping that millennial whisperer Sanders can up her street cred among young voters -- a tall order the self-described democratic socialist from Vermont has taken on.
