Not too much info there really but it mentions this: "The PLA also remains unable to operate joint engagement zones, which are required to enable SAMs and combat aircraft to engage targets in the same airspace simultaneously."
I understand if fighters from both sides are engaged in a close quarter combat, you probably cannot shoot your SAM as it would be difficult to identify friendly from foe. Is there a solution to this? How does modern SAM work with combat aircraft really?
Appreciate if someone would comment on this, thanks

I would say J-10B got AESA, not PESA, although this is an earlier form and the AESA on the J-10C is better.

Other AESA on wings are KJ-200 "Balance Beam" and the KJ-500. I would think that many of these Y-8 and Y-9 variants used for AEW and ELINT are AESA, such as the Y-8 "Mumps".

Surely the PLA SAMs all have mandatory IFF, and all the planes as well. But active homing AAMs and SAMs don't differentiate once they are on the loose.

which is why i dont understand how this "joint engagement zones" works

First operational AESA or at least one of the earliest AESA operational with the PLA, which is a long time ago, was back in the year 2000. It wasn't on aircraft or ship or a SAM battery. It was some sort of artillery or mortar tracking radar. I can't remember the name or designation but it was pretty mobile so it can be used with moving army units at the field. This was followed by AESA units on satellites. By the time AESAs were being used on planes and ships, there was already a degree of considerable background and deployment experience with that technology.

Anybody know if there are any serious projects ongoing or being considered for tandem rotor, coaxial rotor, or tiltrotor aircraft

There are drones using those technologies. I remember at least drones with tandem rotor and tiltrotor.
The PLAN operates the Ka-27 coaxial rotor helicopter. There might be a coaxial drone available but can't remember tbh.
Even if the drones aren't meant to carry humans having them means they solved the fly by wire problems and airframe design problems.

This is J-10B radar. From these angles and radiator antennas, you cannot tell if its AESA or PESA, and parallel line feed PESAs can also use the same radiator antennas as AESA. But this is also a NRIET product, and the products of this institute has skipped parallel line feed PESA as a whole and goes directly to AESA in which this research institute has placed its bets early. NRIET or Institute 14 is also responsible for the Type 346 radars you see on the Type 052C/D and 055 destroyers. On aircraft, their radars are referred to as Type 14XX like 1473, the 14 signifies Institute 14.

Those eight antennas you see across the face of the array are the IFF.
