While other threads have mentioned Japan on its own faring poorly against the Soviets in the event the former attempts to invade the Russian Far East.

What-if via a butterfly netted scenario as part of an ATL East Asian Anti-Soviet/Anti-Communist Triple Alliance Japan was not only joined by a stable post-Qing China (as a constitutional monarchy under the Duke of Yansheng aka Later Yin Dynasty), but also a Korean Empire (that experienced a successful Munjo Reformation instituted by King Munjo later Emperor Munjo, the latter essentially being the Korean equivalent of Japan's Meiji Restoration)?

Since the ATL Empire of Japan is not in much of a position to annex Korea let alone threaten China in this scenario (beyond Taiwan) nor able to capitalize on the weakness of both as in OTL, how would it along with ATL China and Korea deal with the Soviets and the potential threat of Communism? Would they remain neutral like OTL Sweden or like OTL Finland opt to join the Axis in an ATL WW2 (leading to ATL Sino-German cooperation, Anti-Comintern Pact, pre-war German-Japanese industrial co-operation, etc for all three nations).

How would the Soviets respond, are they completely screwed in this scenario if this East Asian Triple Alliance opts to invade? How would the WAllies respond to such a development?

An interesting thing to consider would be this ATL China's potential to play a more belligerent Anti-Western role in this scenario (in seeking to avenge the "decades of humiliation"), on top of OTL Anti-Western sentiment in Japan.

Does some form of ATL Pacific war still happen in this scenario? China would probably be seeking to retake colonial possessions in its territory as well as Outer Manchuria, while Japan would be focused on gaining Northern Sakhalin, Kuril Islands as well as potentially other areas of Southeast Asia with Korea possibly joining in this "decolonisation" effort.

Also beyond the Soviet Union, am curious to know what role the Communists in both China and Korea are likely to play in this ATL scenario beyond evolving into similar post-war analogues of the German Red Army Faction, Italian Red Brigades and Japanese Red Army terrorist groups.

Or is it possible that such a scenario drifts into an entirely different direction, with Japan for example joining the Allies instead due to the potential belligerency of an ATL Axis China/Korea and being in a similar position to the UK in OTL during WW2 as an island nation?
