No matter it's the American strategic masters like Kissinger, or Chinese people suggest Ukraine not to take sides, it is first based on reality, and secondly based on their own interests.
Based on reality, because Russia will not allow Ukraine to be independent. Yesterday, in my article "On the Ukrainian issue, Russia has no choice but Trump will end up with nothing", I mentioned that as long as Russia remains a major power with great ambitions, the bottom line he can accept for Belarus and Ukraine is that both countries remain neutral; exceeding this bottom line will definitely lead to war, which is also my consistent view.
Once the war breaks out, Belarus and Ukraine will have no possibility of neutrality, and Russia can only choose to annex them by force and make them submit. Such a situation is something that neither the US nor China would like to see. However, there are differences between China and the US on the Ukrainian issue. For China, the strategic value of Russia is obviously much higher than that of Ukraine, and the cause of the outbreak of the war is clearly instigated by the US, so we only support peace in the Russia-Ukraine conflict; for the US, they cannot help a strategic rival like Russia, even if Trump takes office, at most there will be some favoritism.
In international issues, different countries and different people may have completely different positions and starting points even when they look at the same event and reach the same "neutral" conclusion.
