The Chinese company Ant Group does a lot of things. It provides loans, mobile payments through Alipay, credit scores, and it acts as an investment platform. Last year, it was headed for what might have been the biggest initial public offering in history, until the Chinese government abruptly canceled it. The government on Monday forced the company under the control of its central bank and demanded that it restructure as a financial holdings company. All this happened after founder and tech billionaire Jack Ma gave a speech critical of Chinese regulators last year. But the obvious story is not the whole story. Molly Wood speaks with Rui Ma, who advises investors about Chinese companies and technology.
