I think you should go back and a bit deeper in history. The Finns were not victims of the Soviet Union, on the contrary it was an example of how a balance can be found so that the country having good relations with both the West and the Eastern bloc. Because of the direct proximity to the USSR, the country's communist movement was not oppressed and purged like other European countries (Rosa's Luxemburg era Germany, Spanish civil war, Greek civil war), but it was able to hold positions of power and actively participate in the country's political life. Also, regarding Germany, the original plan from the time of Stalin was a united Germany that will decide with a referendum the way of governance, something that the rest of the allies rejected and provoked, forcing the easterners to raise the infamous wall. Let's not forget that Berlin was in the heart of East Germany. It's like saying, for example, that in Pyongyang, half of the city belongs to South Korea. West Germany was the de facto heart and initial implementation of NATO, and this continues to this day as the US military occupation continues strong to this day. I could call the not so naïve, perhaps cunning policies of Gorbachev during the period of the collapse of the Eastern bloc and its political and geostrategic decline. To draw safer conclusions you must study bloc's reign and not it's alienated endGeorge Yeo is always such an insightful and elegent speaker. It seems to me the Finns are much more understanding of China than other victims of the soviet.
I already knew what Wang Yi said about China supported German unification, much of it probably because of principle. But it's today I realized that this support came against Russian interests of the time. Russia's reluctantly agreeing to German unification and entrance into NATO laid the ground work for all the NATO expansion Russia is dealing with today.
