China provide military assistance to N. Korea, perhaps with J-10A, GJ-11, KJ-200 etc?

Somebody PS a J-10CK for N.Korea in KPAAF color.

In terms of equipment, logistic and training, people doubt PKAAF can field a modern air force to carry out modern air warfare. Perhaps it still has to rely on the China DPRK defense treaty, and other means for self defense or deterrence. Such assistance can help to beef up at least the air defence. My suggestion is to throw in some air defence missile such as HQ-16FE, HQ-17E or HQ-9BE.

In the recent ICBM test, Hwasong-17 flew close to 1,000km and reached altitude of 6,041km, which give it a range of 15,000km.
