I don’t know how viable would that be on a large scale, but they could just ban all China-based companies from operating outside like the US did with Tiktok.
I think that would deal a decent blow on their economy, but I’m far from an expert in those fields so someone who knows better will probably come and debunk me.
Ehh… that depends too. Here in Italy there’s plenty of people that wouldn’t bat an eye at their 10-year old playing CoD and shooting people in the most graphic ways possible, as long as there’s no female nipples in sight.
