I'm hopefully wrong, but it's really skeptical to see if Ukraine can economically recover quickly from the war or even achieving their equivalent of East Asian economic miracle.

First, the current demographic of Ukraine is worlds apart compared to East Asian countries in the 60s-70s (After WWII and other Asian Wars). The latter have had demographic pyramids resembling more of present day African nations while the former has a demographic pyramid resembling more of Western European nations. We've known the fact that demographic balance is a great predictor of economic success, which means that Ukraine's economy potential has already been crippled in this front

Second, the proximity of Ukraine to wealthy countries that are happily accepting Ukrainian immigrants also hindered their economy growth. Compared this to East Asia back after the war, when their immigrants need to cross continents and oceans to settle in wealthy countries, since all of their neighboring nations were also war torn and poverty stricken, which means that a lot of them stayed to rebuilt their country. A comparison of wages shows that even being a hard laborer in Western Europe yield better wages than working as a mid-level white collar professional in Ukraine. So rationally, why would you stay in Ukraine after settling in other European countries? They have already been bleeding population since the fall of Soviet Union, and I don't think this trend will reverse at all.
