Korean yen
The Korean yen was the currency of Korea between 1910 and 1945. It was equivalent to the Japanese yen and consisted of Japanese currency and banknotes issued specifically for Korea. The yen was subdivided into 100 sen. It replaced the Korean won at par and was replaced by the South Korean won and the North Korean won at par.
Expatriates in the United Arab Emirates
Roughly 1,300 North Korean workers live in the UAE, primarily in Dubai and Abu Dhabi. They earn between US$300 and $500 per month, but must make so-called "loyalty payments" of $150 to $250 to the North Korean government. This has sparked discontent among those workers—and in response, the North Korean government has sent security agents to patrol North Korean work camps and look for people making critical comments.
