What happens when a 50-year business partnership turns into a family feud? In South Korea, two powerful families are now locked in a dramatic fight for control of Korea Zinc, the world’s largest producer of zinc. This isn’t just a corporate drama—it’s a clash that could reshape the country’s business landscape. Back in the 1970s, the Choi and Chang families teamed up to create Korea Zinc, a company that would become a global leader in zinc production. The Chois managed the new venture, while the Changs ran the parent company, Young Poong. For decades, the “two families under one roof” arrangement worked smoothly, helping Korea Zinc grow into a critical player in South Korea’s economy. But now, the harmony has shattered. The descendants of the founders are battling for control, with Young Poong, still led by the Chang family, trying to oust the Chois from their management roles. The conflict has escalated to a shareholder meeting this week, where the Chois will fight to keep their position. This isn’t just about family pride—it’s a test for South Korea’s chaebol system, the powerful family-run conglomerates that dominate the country’s economy. The outcome could influence whether these traditional structures can adapt to modern corporate governance practices. Korea Zinc isn’t just any company. It’s a key supplier of metals essential for global supply chains, with no ties to China, making it strategically important. The stakes are high, and the world is watching to see how this family feud unfolds. Will the Chois hold their ground, or will the Changs take control? Either way, this battle is a reminder that even the strongest partnerships can face challenges—especially when billions are on the line.
