As a Manchu, this looks pretty good... but one question, why is Changchun the capital? It should be Shenyang (or Mukden, the manchu name) for it is the previous capital of the Manchu Empire (aka Qing dynasty) and the historical capital of Manchukuo. And also... Manchuria wouldn't use the Manchukuo flag because we... uh... kinda don't like Japan a lot, even during "those" times.
Because the Soviets found Changchun to be convenient for their purposes, why transfer the capital? And the post-Soviet government deliberately used the Manchukuo flag as an kind of reaction against Soviet rule. They didn't have a proper symbol by then, and re-interpreting the Manchukuo flag seems to be the best they could do. Of course, there are movements that wanted a new flag, but then, most think they have restored the memory of the Qing and Jurchen and consider Manchukuo as a last-ditch attempt for ethnic Manchus to have an homeland, even under Japanese rule. Their war against North Korea vindicated them.
About the peoples of Xinjiang and Tibet in this world, they are lucky to have independence. The Dalai Lama in 1946 wisely asked the UN to let Tibet join despite Chinese protests, this enabled them to resist the Chinese invasion. About Xinjiang, the Soviets annexed Xinjiang in 1946. The Uyghurs regained independence like other Soviet republics, and treated as a Central Asian country, albeit worrying about Chinese immigrants.
Just wondering, why would a post-communist, democratic Manchuria use the same flag as the fascist Japanese puppet state Manchukuo? And I realize that it's based on the Five Races flag, but wouldn't the stigma simply be too great?
It was annexed by the USSR. In the real world Russian is still pretty common in the former republics, mainly as a language for business matters or inter-ethnic communication.
