[South Korean Crypto Exchange Coinone Files Lawsuit Against Financial Intelligence Unit Over Regulatory Sanctions] According to Naver, South Korean cryptocurrency exchange Coinone has taken legal action against the Financial Intelligence Unit (FIU) over imposed sanctions. The company has filed a lawsuit with the Seoul Administrative Court to revoke the partial business suspension order and submitted an application to halt enforcement, aiming to suspend the sanctions before they take effect on April 29. The core of the sanctions involves restricting new users from depositing or withdrawing crypto assets to external exchanges, while existing users remain unaffected. New users will still be able to use other trading functions aside from deposits and withdrawals. Previously, the FIU imposed a three-month partial business suspension and a fine of 5.2 billion Korean won on Coinone, citing violations of the Specific Financial Information Act. The violations were identified during an anti-money laundering on-site inspection and included transactions with unregistered entities, non-compliance with customer verification, and breaches of transaction restrictions.
