I really dont see China relying on Russia, and USA and European trade with China would hit zero, literally turn the ships around, we can manage for 6 months without plastic patio furniture.
Russia v NATO would be over in 3 days, and mostly done by Poland, with air support from UK and france, Germany would arrive in the air on day 3. Then you have a pissed off NATO sending 3 big carriers, plus whatever 6 small carriers, plus 30 frigates out to Taiwan, to meet the 3 chinese carriers, whilst escorting every merchant ship loaded with chinese stuff, back to China.
