On paper, their Tien Kung 2 SAM system appears good enough, and if data is to be believed, it could be one of the best SAMs in the world. Up to 200km in range, has a dual active radar guided and IR seekers, and is guided by a phase array called Chang Bai, which can track about 100 targets and engage 24 simultaneously. That appears to be beat the crap out of the PAC and AEGIS/SN-2 system.
