For the second year running, Japanese Maritime Self Defence Force assets have photographed Chinese naval forces operating ship-based Unmanned Air Vehicles during the People's Liberation Army Navy's annual run through the Miyako Straits between the Japanese islands of Miyakojima and Okinawa. What's more interesting is that this time the Chinese were operating helicopter UAVs, with one, and possibly up to 3 aircraft off the deck of Type-054A Jiang-Kai II frigate Zhou San (舟山).

Greg Waldron over at Flightglobal mentions that the UAVs are most likely Austria's Schiebel Camcopter S-100, with China known to have obtained obtained 18 examples two years ago.
