Tourists and RMB.  Yep, Korea is becoming awash in both.  Quartz article sums it up nicely:

But most of all there is the undeniable appeal of JejuThe resort island off the South Korean coast is drawing Chinese tourists with its subtropical climate, visa-free status, and attractions like casinos and an erotic-sculpture theme park known as Loveland.

In 2013, almost four million mainland Chinese tourists visited South Korea, and 1.8 million of them went to Jeju…If Ctrip’s predictions are correct, the number of mainland tourists visiting South Korea will rise to 5.6 million this year—equal to over 10% of South Korea’s population.

Chinese tourism for 2014 may equal 10% of the ROK’s population?  Holy cow!
