Yes, Ki-43, not an odd P-43 as I first thought. Seems very big compared to the P-40 in the foreground.
There's another photo (same aircraft, I presume) of a 2-bladed Ki-43 at Kunming in 1944 being examined by USAAF & RoCAF personnel:

I wonder how old or how long ago the 2-bladed Ki-43 started service in China to be still there as a captured aircraft in 1944?
