Kuok Khoon Hong is a Singapore business leader in agribusiness and edible oils. He is the cofounder, chairman and CEO of Wilmar International. He started out trading soft commodities at Kuok Oils and Grains and later became managing director there. He also worked on the Pasir Gudang edible oils refining complex in Johor and on South Seas Oils and Fats, described as China’s first edible oil refinery.
In 1991, he left the Kuok Group and cofounded Wilmar with Martua Sitorus. The business grew from a small commodities trading company into one of the world’s largest palm oil producers and the world’s largest palm oil trader. Wilmar expanded in Indonesia, then built a larger refining business in mainland China and formed a joint venture with the Adani Group in India. He also became cofounder and chairman of Yihai Kerry and non-executive chairman of Adani Wilmar Ltd.
How Kuok Khoon Hong built his wealth
Most of Kuok Khoon Hong’s fortune comes from palm oil and the wider edible oils business. He cofounded Wilmar in 1991 and turned it into a major agribusiness group with a strong presence in plantations, refining and trading. Its growth in Indonesia and mainland China helped make Wilmar a large force in Asian consumer markets. A 2007 merger with Kuok Group edible oil, trading and plantation assets added more scale to the company.
His money is also tied to investments outside Wilmar. Forbes notes that he has stakes in Yanlord Land and Perennial Real Estate Holdings. He also co-owns the Aviva Tower in London with Martua Sitorus. In 2020, he listed Wilmar’s Chinese subsidiary, Yihai Kerry Arawana, in a $2.1 billion IPO on the Shenzhen stock exchange. That deal put a public market value on a key part of Wilmar’s China business.
