Two Russians caught in $42M USDT cross-border transfer case in South Korea

A Cambodia-headquartered financial group recently cut off from the U.S. financial system is suspected of having operated in South Korea, raising fresh questions about cross-border crypto and currency flows tied to the group. According to the Dong-A Ilbo, which cited data from the Korea Customs Service (KCS), Huione Group—now sanctioned by the U.S. Treasury Department’s Financial Crimes Enforcement Network (FinCEN)—appears to have run a currency exchange in Seoul from 2018 to July 2024. The outlet reported that a banner on the premises displayed a logo identical to Huione’s, prompting suspicions about its ownership and control.Photo by Aleksandar Pasaric on PexelsTies to North Korean hackersThe exchange reported conducting roughly $20,000 in annual currency conversions during that period, excluding cryptocurrency transactions. The timeline overlaps with a period in which Huione Group reportedly received $150,000 in cryptocurrency from the North Korean hacking group Lazarus.  Connections also extend to Cambodia. Panda Bank—a local lender that shares a building with Huione subsidiaries—supports USDT transactions originating from South Korea. Panda Bank director He Yanming is listed as the owner of Huione Crypto, a virtual asset service provider (VASP), suggesting potential links between operations in Seoul and Phnom Penh. These developments come against the backdrop of a U.S. investigation disclosed in May, in which FinCEN said Huione’s business networks, including payments arm Huione Pay, collectively laundered at least $4 billion in illicit proceeds between August 2021 and January 2025. Crypto used in $2.6B illegal conversionsMeanwhile, recent KCS data also shows a rise in illegal currency conversions involving cryptocurrency by foreign nationals. The Korea Economic Daily reported conversions totaling 432 billion won ($302 million) in 2021, climbing to 836 billion won ($584.5 million) in 2023 and 956 billion won ($668.4 million) last year. Over the past eight years, the total amount involved in such cases reached 3.7 trillion won ($2.59 billion) across 28 instances. By value, Chinese nationals accounted for 84.1% of the total, followed by Australians (11.1%), Vietnamese (3.2%), and Russians (1.6%). The growing prevalence of cryptocurrency in illicit activity parallels a broader surge in crypto investment within the country. Many South Koreans have turned to digital assets, often with home ownership as a long-term goal. Trading on local exchanges, Bloomberg reported, is heavily skewed toward more volatile altcoins, which make up more than 80% of total volume.  That stands in contrast to global markets, where investors largely focus on Bitcoin and Ethereum, which together make up more than half of overall trading. The momentum in local crypto investment intensified after Donald Trump’s U.S. presidential victory, with crypto trading in Korea reaching $27 billion in December 2024, about 80% of turnover on the KOSPI stock index. The investigation underscores the growing challenge for regulators in tracking and containing cross-border financial networks that rely on cryptocurrency and informal money transfers. As crypto adoption deepens in South Korea and scrutiny widens abroad, authorities find themselves navigating an increasingly intricate intersection of financial opportunity, enforcement, and risk. 

China Unveils Offline SIM Card Wallet for Digital Yuan PaymentsThe People’s Bank of China (PBoC) has announced a new offline SIM card-based solution for its digital yuan, enabling users to make payments even with their phones switched off.Photo by Sumeet Singh on UnsplashEmbedded hardwareThe innovative initiative was revealed via a social media post on Monday. It aims to reach users with 2G phones who were previously unable to access digital currency.Currently, this feature is only available for Android phone users with NFC functionality, as no details have been given for iOS users or 2G phone owners. This innovation is part of the central bank’s efforts to expand the reach and usage of its digital currency, especially for users with 2G phones who were previously unable to access it.Earlier this year, the PBoC launched a similar solution for smartphone users, using near-field communication (NFC) technology. However, the latest solution relies on hardware embedded in SIM cards, which can act as a “hard” (offline) central bank digital currency (CBDC) wallet.Partnership with telecoms giantsThe central bank’s partners relative to this particular project include major telecom operators China Mobile, China Telecom, and China Unicom, as well as state-owned commercial banks Industrial and Commercial Bank of China and Bank of China, who have also introduced SIM card-based “hard wallet products.” These developments are expected to significantly improve the payment capabilities and network-free functionality of the digital yuan.To use this feature, citizens have to get a “super SIM card” from their carriers. After they have replaced their existing SIM cards and opened the digital yuan app on their phones, they will see an option to “open a SIM card hard wallet.” This will enable them to make touch-based payments to merchants even when their devices are powered off or lack network connectivity.SIM-based wallets are likely to be particularly useful for those using 2G devices or smartphones without NFC capabilities. Considering that about 20% of Chinese mobile users still use 2G phones, it would make sense for the PBoC to continue working in this direction with future updates.Driving adoptionThe ultimate plan of the PBoC regarding SIM-based wallets is not clear yet. However, recent developments, such as the pilot project in Qingdao where CBDC payments were tested on the metro system without electricity or network, indicate a strong push toward increasing the accessibility and adoption of the digital yuan.Frankly, moves to bring about adoption of the e-CNY have been nothing short of relentless. These measures have varied from paying state employees in e-CNY in Changshu, collaborating with French bank BNP Paribas so that its corporate clients start to use the digital yuan and enabling e-CNY bus fare payments on public transport in Jinan.China’s Jiangsu Province has integrated the digital yuan into its education system, while the resort city of Sanya recently introduced e-CNY ATM machines so that foreign tourists have a means through which they can access the digital currency. These developments demonstrate a clear commitment by the Chinese authorities in advancing the rollout of its central bank digital currency.

China to Pay State Employees in Digital YuanChina is making its biggest push yet to facilitate greater use of its central bank digital currency (CBDC), the digital yuan (e-CNY).©Pexels/RODNAE ProductionsThe eastern city of Changshu is gearing up to commence paying state employees in the city in e-CNY. According to an announcement made by the city’s finance bureau on Sunday, the civil servants will start to receive e-CNY as payment in May. The measure will also impact journalists working for state media, medical staff, technicians and schoolteachers.Advancing a cashless societyThrough a proliferation in the use of digital money such as that offered via WeChat Pay and AliPay, China is already well on its way towards being a cashless society. However, this latest move with the e-CNY is another major step in that direction.In a separate announcement on Sunday, the administrators of the city of Xuzhou, which like Changshu is also located within Jiangsu province, said that Xuzhou is in the process of publishing a pilot scheme which will set out a means for promoting China’s e-CNY digital currency. Meanwhile another Jiangsu province city, Suzhou, was one of the first locations in China to run a digital yuan pilot scheme in April 2020.Previously local government authorities in cities like Shenzhen and Beijing have experimented with using the currency, offering free digital yuan to citizens to spend, in an effort to popularize the digital currency.Changshu had already been using the currency for the best part of a year to make overtime payments to 4,900 state enterprise employees. Additionally, the city administrators had introduced it to pay subsidies, including payments to tech companies, payments related to housing and transport for local government workers. While there’s every likelihood that this latest measure could be applied on a province-wide basis, there has as yet been no direct confirmation of such an eventuality.Privacy concernsThe Chinese government maintains that further introduction of the e-CNY will lead to an improvement for citizens in terms of privacy. Beijing maintains that the large tech platforms like WeChat Pay and AliPay will have no access to the transaction data of individuals and companies. However, that data will find itself directly in the hands of the Chinese government. Given the totalitarian nature of governance in China, it’s hard to imagine how that could be a positive outcome for Chinese society.International currencyOriginally known as DCEP, work on the digital currency began in China in 2014. The Chinese are among a growing list of countries that are understood to be unhappy with the need to use US dollars for international trade given that the dollar is the global reserve currency.That discontent has grown further as a direct response to greater use of sanctions by the United States, and particularly the seizure of Russian sovereign funds held in dollars. Furthermore, the weaponization of the SWIFT payments system exemplified through the exclusion of countries like Russia and Iran is also believed to have been a catalyst for greater development of the e-CNY.
