A transnational law enforcement operation codenamed "Gatekeeper" has recently been shut down. The operation targeted an underground channel that specialized in transporting high-end GPUs to specific regions. Law enforcement agencies confiscated advanced graphics processing units worth over $50 million, totaling more than 5,000 units. These chips were originally intended to be shipped to areas restricted by technology export controls. It is important to note that such high-performance GPUs are not only the core computing power for AI training but also critical hardware for cryptocurrency mining. As countries tighten controls over the flow of cutting-edge chips, such smuggling cases could continue to impact the global distribution of computing resources.
