The Chinese are being pretty open about it and there's abundant footage. I do agree it's qualitatively different. The Chinese ations are also different in that they're being used to assert a territorial claim: China has been building artificial islands (by dumpin large piles of dirt) so it extend its territorial waters. So they always claim the other vessels are violating their boundaries. I presume this is being undertaken with a view to keeping the US and its proxies as far away from their coastal areas as possible in the future.
