The radar system on China's Type-051C & Type 052B class vessels were supposedly built with Ukranian help.One should remember that the Soviets were also working on phased array radars
There is no Ukrain connection here.
The aerial defence systems on 051C and 052B are either imported directly from Russia, or manufactured under license from Russia.
The PAR on 052C is developed indigenously by China's Nanjing Research Institute of Electronic Technology.
