In another anti-monopoly push, Chinese regulators on Tuesday cautioned the country's leading internet platforms on Alibaba's record $2.78 billion fine for abusing dominant market position, and allocated them one-month grace time for rectification.

China's top authorities for regulation of markets, cyberspace and taxation pledged to continue to crack down on internet platforms abusing their dominant market positions in a joint meeting.

The officials said that China required enterprises operating on internet platforms to respect and obey the rules. They ordered platforms to comprehensively rectify problems within a month and establish a new order of platform economy after Alibaba Group's case.

China's State Administration for Market Regulation (SAMR) last week slapped a fine of 18.23 billion yuan ($2.78 billion) on Alibaba Group for indulging in a monopolistic act.

Alibaba Group was specifically fined for prohibiting merchants from opening stores or participating in promotional activities on other competitive platforms – the "pick one out of two" strategy.

Regulators again bashed such a requirement in a statement along Tuesday's meeting, citing the act has curbed competition, infringed the legitimate rights of the merchants, and at the same time hurt consumers' interest.

"If platform companies are caught on implement 'pick one out of two' strategy or other illegal activities after the rectification period, they will be severely punished in accordance with the law," the authorities said.

They also pointed out problems such as unfair price competition among community group buying firms, information leakage and tax-related illegal acts.

Representatives of 34 internet platform companies participated in the meeting.

At the beginning of 2020, China started the process of making revisions to its antitrust law for the first time since it took effect in 2008, with major changes on regulating abuse of market dominance.

China issued antitrust guidelines on the country's platform economy in February, signaling strengthened antitrust enforcement against monopolistic behaviors in the country's internet platform sector.
