G uo Guangchang is a prominent Chinese self-made billionaire and the co-founder and chairman of Fosun International, one of China's largest private-sector conglomerates. Often called "China's Warren Buffett," he co-founded the company in 1992 with several university classmates. They started with a small market research company and have since built a massive global investment empire.

Fosun operates on a model of acquiring and managing a diversified portfolio of assets, with major interests in insurance, pharmaceuticals, real estate, and tourism. The group has made a series of high-profile international acquisitions, including the French resort operator Club Med, the Portuguese insurer Fidelidade, and the English soccer club Wolverhampton Wanderers. Guo's career has been a story of ambitious, debt-fueled expansion, though in recent years, the group has faced pressure to sell assets to manage its high debt load. He remains one of China's most powerful and globally-minded investors.
