Yes, in terms of actually solving the problem, we should also see where China's customers/influencers come from. Countries can (and do) demand that other countries have certain working standards and regulations. On pain of tariff or sanction.

A lot of my goods come from basically slave labor and polluters. They have a competitive advantage over companies who don't, so garbage floats and takes over. Countries are complicit when they support or benefit from other countries which do this.
