Really impressed ngl. Well spoken by Chinese think tanker, (Retired) Senior Colonel in the PLA
He says there could be multiple ways China could contribute in the peace negotiations.
Could be in collective security guarantees to Ukraine (or Russia..).
Participate in peacekeeping operation (station peacekeeping troops I guess) he says that Russia for sure wouldn't accept NATO or European peacekeepers, but global south India or China could be acceptable
Could participate in post-war reconstruction of Ukraine
Finally he answers a question why China builds up it's nuclear arsenal. He says that NATO hasn't sent soldiers to fight Russia in Ukraine, but US is not afraid on not fighting China. Doesn't that mean that US is simply afraid of Russia's nukes and not of China's because of low number of nukes. Very clear answer
Would recommend everyone to watch the entire video
