Well if you're looking at a wanked out version of both, like In Presence of Mine Enemies, pretty much by the time both powers get that way they've gone nuclear and MAD takes over.
You could alternatively keep the Sino-German alliance in tact and see Germany supporting Chiang when Japan invades in 1937, but that's probably not what the OP is going for. Not much influence Germany can bring to bear into that hemisphere anyways aside from advisors and weapons.
