South Korean Regulators Warn Dozens of Foreign Exchanges to Comply With New Rules Overseas crypto exchanges marketing to Koreans will be blocked if they fail to comply with new South Korean regulations. The country’s anti-money laundering body has sent a notice to a number of foreign trading platforms warning them a registration is mandatory in order to provide services to Korean residents. Korean Financial Intelligence Unit Notifies Foreign Crypto Exchanges of Registration Obligations Access to foreign-based cryptocurrency exchanges can be denied and the platforms may face criminal investigations in South Korea if they don’t comply with the country’s new regulations for the sector. One of the key requirements is to register with the Korean anti-money laundering agency, the Financial Intelligence Unit (FIU), by Sept. 24.
