If the missile as you mention is of Chinese origin, what makes you think PAF has not already mated it on JF-17 and just kept it under wraps? HOBS is a significant capability and in dog fights, could be the winning difference.
At this point, we are only losing suppliers for the JF-17 to India''s much larger market. Recently we lost Denel Dynamics who are involved in a lot of programs with the PAF.
