Up to date info on Chinese AEW and ELINT

Learned contributors,
I have found this slightly dated link
http://www.sinodefence.com/airforce/specialaircraft/default.asp
and was wondering if anyone could please point me towards any more recent information on Chinese A.E.W. and Elint aircraft, plus anything at all on an AWACS version of the Y-7 (AN-24).
Thanks in anticipation
Be lucky
David
