The Chinese government needs to investigate, fine, and/or jail the Chinese official(s) for accepting bribery. Of course, China should fine Bankman-Fried/his company too, and a demand for his extradition for bribing Chinese government officials(even if China-USA doesn't have such agreement).
As this Bankman-Fried story is pretty big now, China can ride this news and help it megaphone its message against corruptions. It will let Chinese officials and foreigners know that corruptions against its country will get punished.
