The Kh-59 is a real stand off missile, its normal that China purchased some of them and they can also be equipped with image intensifier’s to work at night, for a weapon of such a class, this guidance method is the only way, the Chinese can like it or not.
The point was that China don’t use EO PGM’s and I also see no developments, they only start to using LGB’s. Iran on the other hand likes EO weapons very much, that’s why I said that the C.701 is an Chinese-Iranian joint project, Iran build its version as the Kosar and China as C.701 for export but as it seems not for own use.

Yes they are armed with C.701 and Iran has started to build own missiles and boats. Its a pretty smart weapon its guidance system is interesting.
