More like that number (at the very least, if not some more) for the KJ-500/A fleet alone.
IIRC, one of the Guancha Trio (or one of the Duos) shows aired sometime ago mentioned that Shaanxi AC is making pretty much Gaoxin aircrafts (which certainly includes AEW&C) exclusively these days. The annual production rate of AEW&C aircrafts is pretty high too (in the high-10s if not more), per @万年炎帝 on Weibo.
Going by Huitong's, the following number of AEW&C aircraft have been ID'ed in service:
-KJ-200G: 5x with PLAAF
-KJ-200H: 6x with PLAN
-KJ-500: 24x with PLAAF
-KJ-500A: 8x with PLAAF
-KJ-500H: 15x with PLAN
-KJ-700H: perhaps 1x entered service with PLAN in June
-KJ-2000: 4x with PLAAF
-Y-8J: 4x with PLAN
For a grand total of *at least* 66/67 AEW&C aircraft currently in active service. For comparison's sake, the U.S. has about 100 split between the USAF and the USN. And additional KJ-700/H are being produced, whereas KJ-600 and KJ-3000 will enter service in the coming years. And then there's the matter of the WZ-9 UAV, which appears to have entered production and would constitute the world's first unmanned AWACS.
Summing up, I expect China to pass the U.S. as the owner of the largest AEW&C fleet in the world within a few years.
