CNBC reports that according to one market observer, China announced new anti-monopoly rules over the weekend, but that’s not likely to have much impact on the market for now.

“The new regulation is still, you know, slightly sketchy in details,” Hao Hong, managing director and head of research at Bank of Communications International, told CNBC.

China’s State Administration for Market Regulation (SAMR) has tightened restrictions on China’s internet giants such as Alibaba and Meituan, and introduced new guidelines on Sunday to curb monopolistic behavior. The new rules formalize a draft that was released months earlier.

Hong said the market needs time to digest the details of the latest anti-monopoly guidelines, adding that China’s internet giants have been operating for years and already have “very solid” market positions.

“The regulation, you know, is starting with a very good intention,” Hong said. “The actual fact is that ... the market position ... of these big internet platforms are very difficult to encroach for now.”
