Mainly for the same reason we are looking to retire or have retired every swing plane in the planet from the F-111 to the F-14 to the MiG-23s and the Concord. It is also for the same reason why every country on Earth has not followed up on their VG designs. In fact, as we moved from the generation that made swing wings, the next generation afterwards were all fixed wing.
The complexity makes the swing wing planes difficult and costly to maintain, and somewhat fragile.
China studied VG from various procured examples of MiG-23s, mainly from Egypt (said MiG-23s are now in display in the Minsk theme part). Originally the intention was not just the Q-6, but even a variable wing version of the JH-7. There may be more.
China rightly dumped the idea when she found out the complexity of such, went completely straight wing on the JH-7, which was inspired by the Su-24. Note how China has not procured the Su-24 either, even though that would also have been a logical plane in China's forces.
You know, the Russians are just looking for a reason to make extra money and unload their Backfires to someone gullible enough.
