Etymology of the Korean currencies
The won is the currency of both North and South Korea. "Won" is a cognate of the Chinese currency unit, the yuan (//), and the Japanese currency unit, the yen (; ¥), meaning "round object". The won is subdivided into 100 jeon ().
Dandong
A substantial portion of North Korea's international trade, both legal and illegal, passes through Dandong and Sinuiju, across the Yalu River in North Korea. China handles roughly 40% of North Korea's worldwide export trade ($1.58 of 4 billion USD) and roughly half of the bilateral commerce with China goes through Dandong which imports $468 million [USD worth of product], according to its Ministry of Commerce. Dandong's annual resident per capita wage income for 2004 was somewhere between ¥9,500 and ¥12,237 RMB and the city's GDP was 3.77 billion USD.
