It looks like advances in Chinese guided missile technology were prominently on display at Airshow China. (paid subscription required)

The China Aerospace Science and Industry Corp. (Casic) showed off new missles, including new versions of its C704 cruise missiles with IIR and TV guidance, both intended for air launch, and the smaller C705 (look at the wheels and display easels on both pictures for scale).

I think that it has a 9 or 10 inch body diamerter, as vs the 12-14 inch for the C704.
