  • Chinese authorities will meet with Alibaba-affiliate Ant to supervise the company on issues such as operating in a market-oriented way and considering customers’ rights and interests.
  • The news of the Alibaba lawsuit comes when Chinese authorities have initiated a rein on its biggest tech firms through regulatory action.
  • Last month, China’s regulators unexpectedly suspected  Ant’s massive initial public offering, days before its planned listing in Hong Kong and Shanghai.
