When the entire global market is dominated by a totalitarian statewith the avowed aim of destroying western industry using forced cheap labour to produce a steel surplus, this is inevitable. This is how China does business.

Punitive import tariffs. Which the Tories refused to let the EU implement, on the basis that TATA would stop making cars in the UK if they did so or something.
Some degree of protectionism I guess- state driven infrastructure projects that a) need a lot of steel and b) said steel can only be purchased in the UK. You could come up with a carbon cost requirement for the steel that would rule out any that came from outside the UK's borders.
