Last month, China's State Administration for Market Regulation (SAMR) drafted new antitrust rules aimed at the country's largest tech companies. It didn't call out any companies at the time, but it declared it would weed out "monopolistic practices" like price discrimination, the use of exclusive agreements to lock in merchants, and the compulsory collection of user data.

Those predictions recently came true, as regulators fined both tech giants and the logistics company SF Holding. What happened to Alibaba? The agency fined Alibaba's investment arm 500,000 yuan ($76,472) for not seeking government approval before buying a 73.8% stake in the department store chain
