Has China signaled back of potential countermeasures/retaliations if this were to go forward?
We are ever moving closer to war, and as so the most important part is expanding industrial capacities. This is bar none the most important response, construction of new weapon production facilities.
Eventually all the US assets in China will be forfeit, and besides that, the aggression war driven by NATO will serve as pretext for massive Chinese counter expansion. As long as there is enough to fuel the war machine, China will get to loot many countries in their entirety to more than make up for any minor gains NATO can do.
The old axis started by annexing 2 whole countries while we just watched and bided our time.
