Su 30 MKI is more Indian than JF 17 is Pakistani. At present, 100% of MKI's production is done in India, including manufacturing of the engine. Unlike that, JF 17 is still mostly manufactured in China and then assembled in Pakistan, with the engine still being manufactured and imported from Russia.
While Pakistan's non monetary contributions to JF 17 design (not requirements) are mostly non verifiable claims on forums and those too limited to stationing Pakistani engineers in China, India has actually designed and fitted most of the MKI avionics..
