Hu became Ant's CEO in December 2019 after a year working as the group's president. Before that, he spent four years as the CEO of Alibaba Cloud Computing. He also founded AliFinance. Hu's resignation comes amid increasing scrutiny of Ant by Chinese regulators. In November, Ant's initial public offering, set to be the biggest ever, was suspended in Shanghai and Hong Kong following a meeting between Ma and Chinese regulators. And in late December, China's central bank and three financial watchdogs said they would urge Ant to implement stricter financial regulations for its banking services. In January, The Wall Street Journal reported that the group planned to restructure itself as a financial holding company overseen by China's central bank. This would subject it to stricter regulations.
