Sam Energy Group Limited, established in 2022 and headquartered in Beijing, is a specialized cross-border energy corporation founded to support China’s national energy strategy and implement the Belt and Road Initiative. Focused on coal operations, Sam Energy Group has developed an end-to-end cross-border trade ecosystem, spanning from resource extraction to terminal sales, while steadily advancing connectivity along the China-Mongolia-Russia Energy Corridor. By integrating large-scale mining resources in Mongolia and centering its operations around the Mandula Port as a strategic hub, the company has established a streamlined supply chain system supported by the Tumen Aili Mine–Hangji Port dedicated railway line. This framework enables a "direct Mongolian coal procurement + bonded warehousing + flexible distribution" model, effectively reinforcing critical energy infrastructure along China’s northern border regions.
