While the position of Chinese currency and the nations allowing direct conversion has increased, there is nothing new about trading in other currencies. Most large companies prefer not to gamble on currencies where one year they might experience huge gains and another year huge losses. The way to avoid that is to convert to the other currency up front.
Lets say currency A is equal to 2 currency B. Now currency A is my currency. I want to buy this item for $2A or what is currently $4B. I make the deal for $4B. Now if I don't convert some A to B to cover it or buy some futures then I run a substantial risk. Lets say I don't and time passes before I have to pay but by that time A is equal only to 1.5 B. Now I have to spend $2.67A to pay. Well, I just lost on currency conversion whatever profit I might have made. So the practice of most large businesses is to convert or protect themselves with futures.
Years ago I'd see orders placed for multi million dollar machinery. I knew one company that ordered $2.5 million in equipment. Heads rolled when it was shipped and cost $4 million.
