About shipping cost and choice of shipping method on product page

Hi guys, I am having difficulties in the set up.
1 – If I choose for a product shipping via AliExpress standard shipping for USA, let’s say my product price will be $10. But someone from South Africa purchase this item and pays me $10, after I fulfil the order I see that for South Africa AliExpress ships only with EMS which cost $48 and I have to pay this to fulfil the order.
Now my question is what set up I must do to prevent loosing money from the shipping?
2 – Is there any way to give a choice for clients to choose the shipping method for their order and pay accordingly? Like the option on AliExpress product pages.
I am looking forward to your help.
Best regards
Ivo
