IAF is in a precarious situation. No IAF BVR missiles can get mid course updates from AEW&Cs or a UAV relay. This means they need to guided by the shooter itself or a buddy shooter, they will be under threat from PL-15 and PL-17 and may not be able to provide mid course updates throughout to ensure good PK. Where as PAF or PLAAF shooter can engage in truly fire and forget tactic, shooter fires BVR and then rely on AEW&Cs or UAV relay to guide the missile via Chinese datalink.
Only solution is to develop a local tactical data link system like Link16 or 17. To update ASTRA missile series to work with this datalink. Re platforms, update SU30MKI, MIG29UPG, LCA and our AEW&Cs with this datalink. Not sure if french platforms can be updated without huge OEM costs.
Till then, IAF will have to be defensive in air to air engagement and relying on SAMs like S400, MRSAM and Kusha (in future for area denial). Longer range air to surface standoff weapons like

, Rudram 2 & 3 will provide deterrence against PLAAF and PAF (they are specially vulnerable to it).
