No Gulf Arab will ever buy Chinese fighters, let alone stealth fighters. US would literally Bomb them to bits before they let that happen. Especially under Trump, who is unhinged about allies being disloyal.In the recent stream, the trio briefly touched on the subject of UAE and J-35AE, and they sounded rather uncertain this time. The TLDR of the TLDR is just politics and "momentum".
The only ones who can buy J-35 will be Pakistan. Iran could buy it if China sells it to them, but China will likely not sell J-35 to Iran.
Actually the best candidate for buying J-35 is Turkey. They have the power to withstand the pressure, like they did for S-400. But I don't think China will sell their weapons to Turkey due to Turkish support for Uyghurs.
My prediction is that China will not sell J-35 to anyone except Pakistan for the next 10-15 years. If the global geopolitics changes significantly in the direction of China and more US allies fall into the China camp, then it might happen. But otherwize J-35 will remain unexported to others.
