I was going to make a similar point - this is a persistent problem anywhere there are profitable fish stocks, and absolutely not just by the Chinese - the French, Spanish, whoever, there are plenty of people at it.
Nobody has yet mentioned the UK, but: reduced regulation on fishing was a big motivator for Brexit, where the campaign had its roots deep in coastal towns.
Well, British fishermen thought we'd be "taking back control of our waters", and wouldn't be in the situation where they have smaller quotas that the large Spanish and French vessels that fish British waters do.
