While Chinese SAM systems are indeed comparable to western SAM systems, it should be noted that those western systems are still vastly superior. For example, maritime SAM systems like the European PAAMS or the American AEGIS are still years ahead of anything China has. Also, Russian SAM systems like the S-400 are still years ahead of Chinese systems.
#1 Europe/USA/Russia
#2 Israel
#3 China
China will NEVER sell it's most advanced SAM system to anyone else. There is something better that China has, or is very close to be being deployed, otherwise there would be no export.
The Type-052D has the second generation AESA after the Type-052C, so the likelihood is that the system is very comparable to anything the US or EU has.
