Thank you for the question. I think there are a few ways of answering it.
The easiest thing is to say that this is a nascent problem. It's quite new, and governments are trying to get a grip on it. It's not the case that governments around the world are doing nothing. I think they are trying to understand it. In some places, legislation has been passed and police have been trained.
The basic difficulty is that this is unavoidably diplomatic. We see, particularly around China, a culture of pre-emptive self-censorship in diplomatic missions. They're worried that if they talk about the behaviour of Beijing in their country, they will upset them and there will be a corresponding response. This is hamstringing us from responding the way we should. We should be much freer in imposing, at the very least, targeted sanctions on perpetrators, even if the perpetrator is an arm of the government.
