Here is a grab-bag of PoDs for Asia in the 1930s.
I’ll concede these are actually limited to China and Japan what-ifs, mostly in political affairs.
Responses to the PoDs are requested, and additional ones, especially on other Asian countries, are invited.
Here we go:
1) Zhang Xueliang (aka the Young Marshal) and/or Chiang Kai-shek attempt to fully resist Japanese from beginning of Mukden incident in 1931 (resulting in full-scale war, then and there, or breakage or delay of Kwangtung Army unauthorized aggression)
2) Soviets counter-intervene in Manchuria against Japanese (outcome is lose, win, partition or settle for status quo ante-bellum) in 1931.
3) Chiang Kai-shek begins to support continuous open resistance against Japan from 1932 (during this year Japanese intentions to create a permanent separatist regime became clear, and Ma Chan-Shan put up episodic, and very popular anti-Japanese resistance)
4) Japanese Navy grabs Hainan island before 1937 (in OTL they did not grab it until 1939 or 1940, depending on which of my sources is accurate)
5) No Tanggu truce, May 1933
6) Japan does not retreat from Shanghai in 1932 or 1933
7) No He-Umezu agreement and accompanying Chinese concessions in June 1935 [results in a) less humiliation for China, without additional cost or b) immediate fullscale war in 1935.]
8) AHC/PC: Fullscale Japanese invasion of China prior to Long March
9) AHC/PC: Mao never needs to retreat from southern China
10) AHC/PC: Zhang Guotao becomes main Chinese Communist leader instead of Mao from mid-1930s on.
11) Japanese military factional coup or 1932, 1936 or another year succeeds in establishing new regime
12) AHC/PC: Japanese invasion of Outer Mongolia before July 1937
13) Japanese civil government reins in military adventurism and assassination, without coopting expansionist agenda, between 1931 and 1937.
14) AHC/PC: Japan picks a fight in a territory to the south of China within the 1930s (examples: attack on French Indochina, Thailand/Siam, Dutch East Indies or Portuguese, British or American colonies). Bonus points if they pick the fight with one, but not all.
15) Chiang Kai-shek politically finished, exiled or killed in political tensions at any point prior to fullscale war with Japan.
16) Sino-Japanese military cooperation against western interests in Asia (not necessarily involving shots fired in anger)
17) AHC/PC - No US silver purchase act in 1930s. Effects on Chinese, Japanese and global economy
18) AHC/PC: Communist take-over of national power in China during 1930s
