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:
There are sseveral hypotessis on why pork is banned.
One is that as iraq began turning into a dessert it became economically unviable and enviormentally destructive. So you begin seeing less pig remains starting from around the year 2000. This would have eventually lead to a ban on pigs specifically posibly identified by hoof shape.
Then there is the disease argument. The more your foods physioligy resembles yours the easier for its parasites will grow on you. And the more varied your diet the more types of parasotes you come in contact with. Eating omnivores or animals high in the food chain is a bad idea. But an animal that chews cud is going to be relativley safe. So this is actually a good rule of thumb about what to eat if you ever fond yourself in a place with unkown fauna.
The opsite is true for the prohibitions on alcohol. If you find yourself in a place of doubtful higyne fermented or boiled stuf is best. Microorganisms that live in alcohol or vinager are not harmful to us.
