For example, steel producers outside China simply cannot compete with Chinese producers who enjoy low wage rates and government subsidies. A government like China can shift subsidies and trade policies to encourage any domestic industry and virtually destroy any foreign industry. Trump is right, AGAIN!
Yes, we do not live in Utopia.
And as you say particularly with reference to steel making, it is no secret that China virtually ignores energy pollution in its production, nor does it follow similar policies other western civilized countries do with respect to employment.
