If we look at this article, it gives reference to the Super Seven project which was a redesigned F-7 of which China based the FC-1 project. The F-7 in turn being a upgraded variant of the Mig-21.
Also this excerpt from the book written by Saghir Iqbal, an intelligence analysis, clearly outlined the connection between the MIg-21 and the JF-17.
And finally this excerpt from Flight Global shows how the pre F-7 (MIg-21) differs from the Sabre II. The Sabre II being then used as the basis for the FC-1.
So please lets continue to see anymore of your baseless fabrication and outright twisting of facts while presenting none of your own. This will not be the first , nor the last time I have dealt with people so swelled with Jingoism and blind nationalism that they can take no criticism or reason. Or take exaggerated relish to nitpick even the slightest fact.
Pardon, but are we here at the SDF a bit better that this? If we look at every article that is published in the net while NOT checking the facts then we indeed would believe that China sells Pakistan the Liaoning.
So, come on and do you homework instead of look for stupid reports with wrong facts only since they fit an agenda.
