Economies pushing more trade in RMB

South Korea, which sends around a quarter of its exports to China, is one of the few countries in the world to run a trade surplus with the Asian giant.

South Korea gets components and resources from China and sends back semiconductors, machinery, cars, ships, mobile phones and television sets. In March, South Korea enjoyed an $8.4 billion trade surplus. Last year, trade between the two countries added up to $290 billion.

Both countries want more of this trade to be done in yuan, which would make trade cheaper by avoiding the need to convert funds into US dollars or euros before completing trades.
