W ei Jianjun is a self-made Chinese automotive tycoon and the founder and chairman of Great Wall Motor, one of China's largest and most successful private-sector automakers. He took over a small, debt-ridden, collectively owned enterprise in the early 1990s and transformed it into a dominant player in the Chinese market. He achieved his initial success by focusing on the then-niche market for pickup trucks, which he built into the best-selling brand in China.

He then brilliantly anticipated the boom in the sport utility vehicle (SUV) market, launching the Haval brand, which became a massive success and the best-selling SUV brand in China for many years. Under his leadership, Great Wall has also expanded into the electric vehicle market with its Ora brand and into the premium SUV market with its Wey brand. He is known for his tough, hands-on, and often military-style management approach. His family's controlling stake in the publicly traded company is the source of their multi-billion dollar fortune. His wife, Han Xuejuan, is also a major shareholder.
