The billionaire founder of the Chinese Internet giant hasn't been seen in public in months after criticizing government regulators.

Ant Group's wealth management services are illegal and the company must undergo major restructuring to come into compliance, regulators say.

China's State Administration for Market Regulation is focusing on allegations that Alibaba forces merchants on its website to sell only on its platform.

The initial public stock offering of the Chinese financial company Ant Group, which would have been the world's largest stock offering of all time, has been put on hold.
