Considering no JF-17 has actually been seen with WS-13, his claim is probably false. Also, like triple digit J-10CE and two batches of GJ-21 already sold seems outlandish and rather fishy as well.

2 There is no update on suppose FA-50 Egyptian deal, likely goes to J10CE.
There is a 12 J10CE Indonesia signed, according to Allen.
3 Countries with J10CE rumor: Egypt, Indonesia, Uzbekistan, Bangladesh
4 Countries with JF-17 rumor: Sudan, Saudi Arabia, Indonesia, Morocco, Ethiopia, Nigeria, and authorities in eastern Libya, alongside previously acknowledged discussions with Bangladesh and Iraq.
