I could be reading it wrong. The government invested 100m+ yuan into the company CellX last year so I wouldnt be surprised if it were subsidized. I can't find any up to date information of other types of cultured meat, seems pork is the cash cow right now. Comments on similar articles says the meat is only available in restaurants right now.
:some-controversy:
The US already bans Chinese beef import
Probably protectionism for the US industry/lobbies.
In fact, the only 3 meat products that can be imported into the US from China is raw catfish, processed chicken and processed duck as per https://www.fsis.usda.gov/inspection/import-export/import-export-library/china
