Transit Visa with Turkish Passport

Hello!

I am a Turkish citizen and will have an 18-hour transit at Shanghai airport. I applied for the China Transit Visa and satisfied all the requirements. My application has still been denied because "Turkish citizens can only enter China through invitation".

I find this hard to believe and cannot find any information supporting this claim. Does anyone know if this is indeed the case? Should I go back and apply again?

Thank you so much
