what's the point of selling your products to India in rupee, when there is not much products and services to buy from India using their rupee.... that's why rupee is worthless.. India has lots of black cobras unless you want to use their rupee to buy the cobras...
If you sell your products and services to China in Yuan, you can use the Yuan to buy many products and services from China with their Yuan... that's the values of Yuan...
If you sell your products to Singapore using China Yuan, you can use the Yuan to buy many products and services from China...
If you sell your products to Singapore using Singapore dollars, how many things can you buy in Sin dollars in Singapore.... not much?
So you only want to sell your products in Yuan to Singapore..... Singapore has to buy Yuan first and give you in Yuan to buy the products.
