There are real hatred of china in turkey too. We should have manageable relationship and weakening turkey at the same time too.Actually, I would totally work with Japan and Korea if they are open to it, but there are real hatred in those countries for china defeating all of their national champions and deindustrializing them. Even still, china should still have manageable relationship with these two countries while trying to weaken them at the same time.
Why would you need to sacrifice relationship with Saudi and Egypt to have better relationship with turkey? That's nonsense. You might want to take a look at recent survey from arab countries about their view toward various powers. Guess what, china and turkey ranked the best on that list. So unless you can show evidence that arab countries hate turkey, them your argument doesn't work.
Stop using public opinion of countries to determine foreign policy especially for Arabs countries (Don't have elections). In those countries public opinion doesn't work like other parts of the world. Also Egyptian opinions.
