Understandable. I support abstention, but I also admit that our abstention is irresponsible and selfish.
USA has also supported Israel on many occasions when the world is opposed. China at least abstained from voting, but did not vote No. Compared with USA, we still have a bottom line.
I understand Ukrainians' anger at China, so I just asked the embassy to evacuate the overseas Chinese quickly. We will return to Ukraine in a few years, after all, people's thoughts will change. For example, Chechens now support Putin and Russia very much. Syrians used to blame China for preventing the United Nations from sending troops to Syria, now they thank China.
Before the Ukrainian govt recognizes the independence of Crimea, Donetsk and Lugansk, China cannot recognize the independence of these three regions, nor will it recognize Russia's sovereignty over Crimea.
China's principle is that unless the central govt allows, it is illegal for a region to vote for independence by itself, and China will not recognize it.
Therefore, even if Russia and China have good diplomatic relations, Putin must let the Ukrainian govt recognize the independence of these three regions first, otherwise China will not support him.
