If China ever invades Taiwan, which countries will fully support china??
The actual technical term would be armed reunification (AR). It's the Chinese mainland finally taking back it's Taiwan island that has been stolen away by foreign powers, remnants of the previous government, or in today's case, renegade traitors.
When China goes into AR mode, it won't be looking for approval from anyone. All it wants is for others to get out of its way. The US, and Japan are the principle adversaries who have expressed intent to get in the way. So China is preparing a military that could hopefully keep them out of the way, or failing that, blow them out of the way.
I guess Russia, Iran, North Korea and Pakistan will be the major 4.
Many African countries too.
I would agree with this. South Korea and India might have plans to backstab China during a major conflict like AR. So North Korea and Pakistan will have rather important roles to play in supporting China.
Hell no for me. Turkey has proven to be duplicitous to both Russia and China. Turkey supplies weapons to Ukraine and remains one of the major patrons of ETIM. When China gets into a conflict, I would watch Turkey with suspicion.
Western world will condemn it and apply sanctions( they better try).
Any guesses?
For sure. The Americans, via the Republicans have telegraphed to everyone that they'll throw the mother of all sanctions at China. My guess is that it'll be similar to what has been done to Russia, only much bigger. But this time, the West and it's pets will feel pain on a much greater magnitude.
