China was asking Russian electronic firms for help in developing the radar system for the j-20 less than ten years ago. Now it certainly could be the case that they have been massively funding the progress in that field. I get the feeling that PESA offers similar abilities at lower cost and that Russia is holding off until the change in capabilities is enough to warrant the cost.
For the J-16 all they needed was a radar that was good enough in comparison with the older Russian radar in the Su-30MKK.
You should not underestimate the Chinese electronics industry. The Chinese are one of the leading manufacturers of telecommunications equipment. The basic technology for cellphone stations and antennas is not that different from the one used in radars. Those also use GaA and GaN. They also operate at similar wavelengths. The Chinese also have one of the best semiconductor industries. What they might have lacked was the expertise on the basic algorithms and radar design proper rather than the fundamental electronics technology and the ability to manufacture it in quantity. What makes the most sense to manufacture for Russia and China is likely not the same since the manufacturing expertise domains are also not the same.
You are correct about their telecom work and bring up good points. I don't doubt the abilities of mainland China one bit. In fact I have a serious concern that they will surely overtake us here in the west very soon. I'd say that this is s bad thing but frankly I loathe western politicians nearly as much as the leadership over in mainland China.
My previous comment was more a bitter swipe at western military analysts and their strange biases.
