A chinese Hawk II.

Another caption suggests that it is a Polikarpov I-15bis. I am not really sure, both were operated by the Chinese.

Defending at the Salween River

This is something interesting. The caption says that this is a Chinese made aircraft, picture taken 1938. I didn't even know that the Chinese built planes at this time. Unfortunately, it doesn't say how this type is called. Anyone with more information?
