A year ago, the country was in the midst of establishing currency swap agreements with trading partners, including South Korea. Various currency experts saw the moves as part of a plan to make the yuan more of an international currency - but the lines got little use.

The move "suggests a new and more substantive evolution" toward internationalizing the two countries' currencies, says Marc Chandler, chief currency strategist at Brown Brothers Harriman.
