Liz Truss wants the UK, EU and US to cooperate on dealing with Chinese subsidies that they think make trade unfair. Well, the UK left the EU's trade remedies system that imposes tariffs on China for its subsidies, but the Trade Bill hasn't passed to set up the UK system yet.

As some have pointed out, it's fair to say that the EU is tougher on Chinese subsidies than the UK plans to be with our new system. We've set up a system that is heavily skewed towards keeping duties down or rejecting them altogether based on the public interest.

And often there is just one UK manufacturer of a product asking for duties on unfairly subsidised or dumped Chinese products that has to spend a large amount of money to go through this process and face off with Chinese government lawyers. So we have weakened ourselves.

The EU has decades of experience in dealing with Chinese subsidies, while our officials have no experience. The EU cleverly uses figures from "analogue countries" such as Turkey instead of taking unrealistic Chinese sales data. Will the UK be tough enough and clever enough?

At the end of the process even if trade remedies official recommend imposing duties on Chinese manufacturers, the secretary of state for international state can overrule this arbitrarily and refuse to impose them. Perhaps after lobbying from a rival sector, eg car manufacturers.

And will UK officials have the tools, knowledge and power necessary to identify Chinese circumvention of the duties, for example via Vietnam - a country in CPTPP, which we have asked to join?
