More specifically they want to make sure that they can wipe out the US for at least once. For Russia they already have more than enough intermediate range missiles.
GAIC developed FTC2000G mostly based on demands from small African countries. Those countries do not need modern fighter jets. They are actually in need of planes which can patrol their skies and attack ground targets if required. They are looking to finally get that perfectly from FTC-2000G...

J-20 starts from 00:31:00. It seems to me this time the pilot had pushed the aircraft a little further than the opening day demo flight.

They built up a massive database on several designs of J-9 with data they collected from wind tunnel tests for years. Because there was no fly by wire technology with good enough flight control computers during that period of time, the canards could only have fixed AoA and they had to iterate...
Export some of it with stealth UAVs to developing countries!!! They are not having massive satellite constellations like China. So UAVs can help target something like aircraft carriers and the customer can use this missile to hit it.
