The 1980s was a period of currency shortage in South Asia. South Korea's moneymaking technology was key to countries like India, Bangladesh, Bhutan, and Pakistan, where "made-in-Korea" banknotes and coins were circulated. Further, South Korea's moneymaking technology was transferred to some countries like Bhutan to produce currency. Such export of currencies and technology transfer from South Korea to South Asia is significant in the sense that possessing and producing unique national currencies is closely linked to state legitimacy and power.
