"How long do you think it will be before China figures out a trade war with the U.S. isn't in their best interest and they come to the bargaining table?"

China wont do that because you cant compare China to Europe as the circumstances are much different. Its in China's interest for the Dollar to be valued much higher than the Yuan in the central banking system, as long as the dollar is valued higher than the Yuan China is making money, but at some point Tariffs undermine China's advantage of having a devalued currency and will force them to liquidate their US treasury holdings to assist in crashing the dollar, because at some point the central banking system will no longer be profitable for China.

After China uses its US treasuries to assist in crashing the dollar it will make new trade deals with the United States as China will want the current deficits repaid in the new currency which has equal value to its own rather than the current one which is valued in debt.
