Let me put it this way. You know nothing about the tasks facing the Chinese Air Force. Because the Air Force wants to seize air superiority within the first island chain, the Chinese Air Force only wants heavy fighters. The existing heavy fighter production capacity is not enough for the Chinese Air Force, so how can it be exported?
Why does Chengfei have J36? That is to cope with the extreme demand of the Chinese Air Force for heavy fighters.
And, you pay attention. China is currently exporting medium-sized fighters, whether J10 or J35, because the Air Force is not interested in them. Their range and combat capabilities cannot be compared with heavy fighters, and they cannot effectively complete the Air Force's tasks. The only reason why the Air Force has to equip them is because of the economy.
There are only interests between countries. Trump illustrates this point well.
If China attacks Taiwan, Europe and the United States will immediately lift sanctions on Russia, and then you will see how Russia will treat China?
I think your thinking is very old-fashioned and naive. This is a world of jungle law, which has never changed.
Trump has torn up so many treaties, what are the consequences? Israel bombed Iran, what can Iran do?
