1. Guo Guangchang The 54-year-old businessman who’s often compared to Buffet is a bellwether in more ways than one. One of China’s richest men and biggest investors, he was briefly detained in 2015 amid fluctuations in financial markets. Six years later, Guo’s experience is increasingly reflective of President Xi Jinping’s crackdown on private sector tycoons, most famously Alibaba founder Jack Ma. Yet Guo, the founder of Fosun International, survived that 2015 incident and has expanded his portfolio to include even a British soccer club. As tensions rise between China and Taiwan, he’s now pitching a dose of vaccine diplomacy as the cure, offering to share COVID-19 shots with the self-governing region.

2. Jorge Paulo Lemann He doesn’t eat burgers but there’s no questioning his appetite for food and beverage companies. The Brazilian billionaire investor holds the reins to Burger King and AB InBev, which owns Budweiser and Stella Artois beers. He worked with Buffet to set up Kraft Heinz, though he stepped away from the company’s board in March. And at 81, his hunger for work remains undiminished — he’s shocked that people in Switzerland, his adopted home, retire at 60. It’s that competitive drive that took the former tennis pro all the way to Wimbledon in the 1960s. Six decades later, he’s still serving aces.
