W ang Wenyin is a self-made Chinese industrial magnate and the founder and chairman of the Amer International Group, a massive and powerful private company in the metals and mining industry. His is a classic Chinese rags-to-riches story. He grew up in a poor rural family and started his career in the early 1990s as a warehouse manager. He later started his own business making power cords and cables, which became the foundation of his colossal industrial empire. He built Amer into a global giant with a primary focus on the copper industry.

Amer International has operations that span the entire copper supply chain, from mining and refining to the production of advanced materials. The company's massive growth has been fueled by China's huge demand for industrial metals for its infrastructure and manufacturing sectors. Amer is now one of China's largest privately held companies and a major force in the global non-ferrous metals market. He is known for his low-profile but highly effective management style.
