From my limited ability to comprehend this language, it seems as if the argument with the aforementioned 'hole' is the intent of the military of Pakistan to supply military equipment procured from other suppliers to the Chinese military, so that the Chinese military can study these equipment and decide weather it is worth the time to reverse engineer these equipments and produce a cheaper version or incorporate the technology gathered from the study of these equipments into other on going or future projects for the military.
As for my insignificant opinions on this, well what is the problem here if Pakistan and China think this can help, why not. After all they are strong allies who have co developed military projects before, Infact it will be naive not to do this.
For this particular platform well the Chinese seem to have access to much better technology if they were indeed in the mood for some good old reverse engineering.
