What does it mean to say you get lower labor cost and government subsidy issues? Are you saying the tariffs are disproportionate to the impact of the subsidies? Temporary price distortions eliminate competition, not encourage it.
These are the arguments in favor of tariffs on Chinese autos, I understand they cause a disparity, and yes, IMO they are disproportionate.
Typing the three letters in “IMO” is most certainly easier than doing/documenting complex financial analysis.
