W illiam Fung, along with his older brother Victor Fung, is the honorary chairman of Li & Fung, a major global supply chain and logistics company based in Hong Kong. He represents the third generation of the family's business, which was co-founded by their grandfather in 1906 as a traditional trading company. William, who holds an MBA from Harvard, and his brother are credited with transforming the family's old-style business into a modern, sophisticated, and technologically advanced global supply chain manager.

At its peak, Li & Fung was a dominant force in global trade, acting as a crucial intermediary that managed the entire production and logistics process for major Western retailers, sourcing goods from a vast network of factories across Asia. William served for many years as the group's managing director, overseeing the company's day-to-day operations. However, the business has faced significant challenges in recent years due to the rise of e-commerce, which has disrupted traditional retail supply chains. In 2020, the Fung family, in partnership with a Chinese logistics firm, took the company private to restructure it away from the glare of the public markets.
