Since all puppet regimes where officially merged in 1940 under the Wang Jingwei administration (with the de jure exception of Manchukuo and de facto exception of Mengjiang), its mention might suffice without bothering to include things like the Dadao Municipal Government.  
 ::BTW, wouldn't it be useful to create a "Collaborationist Chinese governments" articles which would mention all these entities, linking to all the governments' individual articles ? I also wonder if Collaborationist Chinese Army could not use a title like "Collaborationist Chinese armies", since there was more than one.
