T ang Ye is a Chinese billionaire whose wealth is derived from his stake in the metals and mining giant, Amer International Group, one of China's largest and most powerful private companies. The company was founded by the self-made industrialist, Wang Wenyin, who built a colossal empire in the non-ferrous metals sector, with a primary focus on the copper industry. While Wang is the chairman and public face of the company, Tang has been a key executive and a major shareholder.

Amer International has grown from a small wire and cable manufacturer into a global giant with operations across the entire copper supply chain, from mining and refining to the production of advanced materials. The company's relentless expansion has been fueled by China's massive demand for industrial metals for its infrastructure and manufacturing sectors. Tang's wealth is derived from his substantial ownership stake in the massive, privately held industrial enterprise.
