The UK and EU secondary sanctions are new - literally within the last few months. The US has used secondary sanctions so widely that we may start seeing other countries following suit, as the UK and EU have very recently started to do. On the other hand, I'm unaware of any Chinese secondary sanctions. Maybe there's some example, but the fact that it's difficult to even find any examples illustrates my point: the US' extensive use of secondary sanctions is far beyond what any other country does.
