Most likely war or if the west is actually stupid enough to do something like the sanctions against Russia against China.
Basically, that card is only gonna be used when it's needed, and not for something more petty or stupid like say the EUV ban/sanction.
It’s a “nuclear option” imo. Using it is essentially a 1 time option because there won’t be a next time to effectively use it. Similar to the West weaponizing the dollar against Russia since it will be significantly weaker the next time for example China. Don’t use it unless you are absolutely sure compared to the West who prematurely threw all their cards against Russia.
