Same reason it’s Japan, Germany, China, etc.
I thought it had been accepted as an exonym, not just an endonym
It’s still gaining acceptance. The Turkish government doesn’t get to decide their own name any more than the CPC gets to decide what the english term for the Communist Party of China is or any of dozens of indigenous american tribes got to choose their tribe name english or what they’re referred to as collectively.
(to be clear, it’s needlessly disrespectful not to use what they tell you their name is)
Communist Party of Zhōngguó
Fixed that for you.
Sure, but you can’t expect english-speakers to pronounce tones. Imagine Georgians expecting english-speakers to pronounce საქართველო or god forbid, or Bantus expecting english-speakers to pronounce their term for South Africa in Xhosan.
I reckon i could have a stab at Xhosan, but only because I’ve watched so much Xhosan rugby commentary (the passion they have for their team is absolutely infectious and carries a game: https://m.youtube.com/watch?v=KPpVLIpt9eg&pp=ygUWeGhvc2EgcnVnYnkgY29tbWVudGFyeQ%3D%3D)
