The J-20 is an ‘invisible’ 5th generation fighter aircraft developed in recent years by China.

Initially, Western analysts believed that China would sell the aircraft to its military allies.

On the contrary, China wants to keep the technology and capabilities of this aircraft away from “enemy eyes”.
This policy was also followed by the US for the F-22 aircraft. So China decided to ban the export of this weapon. It is believed that the financial gain that will come from the sale of the aircraft is not worth leaking technology. This is also the case with other advanced Chinese weapons.

But Chinese experts say that if the United States decides to give the F-22 to its military allies, then China is likely to act accordingly with its own allies in order to strike a balance of power.
