The Industrial and Commercial Bank of China (ICBC), the world’s largest bank by asset size, has long operated behind a formidable wall of state-managed secrecy. Now, an unprecedented leak of more than 4.8 million confidential records from two of its U.K. units lays bare how financial protocols routinely took a back seat to Beijing’s broader geopolitical ambitions.
Inside the Vaults of the World’s Biggest Bank
The investigation, conducted by the International Consortium of Investigative Journalists (ICIJ) in collaboration with 23 media partners, provides a rare window into the decision-making apparatus of ICBC. Published in September 2026, the “China Capital” project examines how state-owned banking institutions advanced political goals through strategic lending, often bypassing ordinary commercial safeguards.
ICBC’s London operations served as a critical financial hub during a period of rapid Chinese ascendance. Internal records show that government influence and political priorities frequently superseded standard banking protocols, allowing the institution to support firms linked to autocrats and oligarchs while aligning with Beijing’s foreign policy objectives.
Financing Huawei and Managing Sanctions
Among the most striking disclosures in the leaked documents is ICBC London’s handling of accounts tied to the Chinese tech giant Huawei. Records reveal that the bank helped Huawei spirit $1 billion out of London just days after the United States unveiled an indictment against the technology conglomerate.
The investigation also exposed how ICBC used its London footprint to finance companies linked to sanctioned Russian and Belarusian business owners, even as Western nations implemented strict financial penalties to disrupt Russia’s military operations in Ukraine. For instance, ICBC London maintained accounts for a U.K. subsidiary of Zoomlion Heavy Industry Science and Technology, a Chinese construction company.
Zoomlion utilized this subsidiary to partner with MAZ, a Belarusian state-owned firm, to construct an industrial park near Minsk. This partnership persisted even after the European Union and its allies sanctioned MAZ due to its ties to Alexander Lukashenko’s regime. Although MAZ officially exited the joint venture in 2023 following U.S. sanctions, records obtained by the Belarusian Investigative Center indicate the firm devised a workaround to continue supplying heavy vehicles to Zoomlion through an unsanctioned party.
Energy Investments and Renewable Strategy in Europe
Beyond corporate tech and industrial partnerships, ICBC targeted key energy and infrastructure assets across Europe. In the United Kingdom, reporting by The Times revealed that ICBC issued nearly $1.7 billion in loans and borrowing options to local water and energy infrastructure companies. Several of these entities had high debt levels, with private owners borrowing heavily against relatively guaranteed incomes to maximize dividend payouts.
This financial model could leave water companies at risk should disputes arise over the debts, The Times reported. Internal memos from ICBC London nevertheless highlighted that participating in wind farm financing was strategically important to maintain relevance within the U.K. renewables sector. These revelations triggered parliamentary debates, with members of the House of Lords raising concerns over Chinese ownership of water utilities and critical local infrastructure.
Meanwhile, in Sweden, Göteborgs-Posten uncovered ICBC’s interest in financing the country’s top oil producer, Preem. Internal bank documents demonstrate how ICBC offered loans to secure access to proprietary technology, specifically processes used for refining waste oil from cooking and forest biomass into premium products—a process of particular interest to China.
Chinese authorities also approved two institutions as joint renminbi-clearing banks, a move designed to streamline transactions in the Chinese currency across 19 countries where Standard Bank operates.
Weighing the Strategic Cost of State-Directed Finance
The China Capital findings illuminate the complex friction points between global commercial banking and state-directed foreign policy. By embedding itself deeply into Western infrastructure, renewable energy projects, and trade clearing networks, ICBC has demonstrated the profound reach of Beijing’s financial diplomacy.
As international regulators digest the scope of these leaked documents, questions remain over how Western jurisdictions will monitor state-owned financial institutions operating within their borders. How should regulators balance the influx of foreign capital into critical green infrastructure against clear national security and compliance vulnerabilities?
