Korean currency
In 1902, won was introduced as the official currency unit replacing yang at 1 won = 5 yang. The bank of Korea was established 1909 but soon after in 1910, Imperial Japan annexed Korean Empire. Under Colonial rule, the country was made to use the currency unit "yen" in the name of Korean yen, which took over the Korean won at par. After the division of Korea, the state of South Korea was established and recognized in 1948, and won was again made the official currency of the new state. "jeon" was made the subunit of the currency that divided it into 100 equal parts. Bank of Joseon issued the currency for independent South Korea for the first time that too in banknotes only.
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.
