A Chinese solar energy tycoon has replaced e-commerce giant Alibaba's founder Jack Ma as the country's richest man with a fortune of $26 billion, a wealth survey showed yesterday. Li Hejun, founder and chairman of Beijing-based Hanergy, saw his wealth nearly triple from a year ago, according to the Hurun Report's Global Rich List 2015. He is now the wealthiest person in China and his global ranking went up 108 notches to number 28, the list showed. Ma claimed the title in mainland China last year after Alibaba completed the world's biggest IPO with its $25 billion listing on the New York Stock Exchange in September. He dropped to third place in the country with a fortune of $24.5 billion, it said. Ma was overtaken by Li and property baron Wang Jianlin, owner of the sprawling Wanda Group whose net worth was estimated at $25 billion, the report said.
