Zhou Qunfei

Zhou Qunfei, one of China's richest women, was seated between Tim Cook and Elon Musk—two of her biggest clients—at Xi Jinping's state banquet during Trump's Beijing visit in May. She made her fortune supplying iPhone touch screens: as a teen, she dropped out of school to work at a watch lens factory, then founded Lens Technology in 2003, growing it into a manufacturing giant making parts for smartphones, computers, smart wearables, electric vehicles, and, increasingly, humanoid robots.
