China Mengniu Dairy, a leading Chinese dairy company, saw its stock price plummet after it was implicated in a major melamine milk scandal in 2008 that sickened thousands of children. While Mengniu's operations and products were not directly involved, the scandal severely damaged consumer confidence in the company. However, major investors like KKR and Goldman Sachs began acquiring stakes in Mengniu in 2009, signaling their belief that the company's brand and operations could recover over time. The Chinese government also took steps to reform the dairy industry and improve food safety standards following the scandal.
