I have been charged 51 yuan (including tacking number) for 36g small parcel from Shenzhen to Russia. Please let me know whether it's correct or not.

Hello,
I wanted today to send a small parcel (1,8 kg) from Tibet Main Post office in Lhasa to Austria.
The Post employee said to Austria there is only airmail service no SAL and no surface mail.
Is that true?
Best regards,
David

Dear Sir/Madame,

I do not know China EMS is the same company with China Post Airmail Parcel.
Our supplier in China will send a Cargo from China to Turkey by China State Airmail Services.
1-) To whom (China EMS or China Post Airmail Parcel) do they deliver the Cargo?
2-) How do they guarantee the transport way to Turkish PTT International, instead of changing the way to the private Cargo companies such as TNT.

Your answer will be kindly helpful for me in our business supply operations from China to Turkey. Thanks.
