China's Ministry of Commerce (Mofcom) said it is "strongly dissatisfied" and "firmly opposes" the United Kingdom's decision to bring British Steel into public ownership on July 16, 2026, escalating a dispute that pits industrial policy against bilateral investment treaty obligations (The Guardian; Euronews).

Prime Minister Keir Starmer confirmed the nationalisation on July 16, in what The Guardian described as "one of the last significant actions overseen by him as prime minister." The transfer was carried out through regulations signed by the UK Industry Minister, following the passage of the Steel Industry (Nationalisation) Act (UK Government; The Guardian).

British Steel had been owned by China's Jingye Group since its acquisition of the assets in 2020. The crisis that led to nationalisation came to a head in April 2025, when Jingye threatened to walk away from the company without preserving the blast furnaces at its Scunthorpe site in Lincolnshire. Blast furnaces are the core equipment for making steel from raw iron ore, and shutting them down typically signals an end to steel production at a site. The UK Labour government responded by recalling parliament in an emergency session to prevent British Steel's closure, passing legislation that granted the government operational control (The Guardian).

The UK Department for Business and Trade said nationalisation was essential to maintain steel production at Scunthorpe and to protect UK supply chains. The move is intended to safeguard approximately 4,000 jobs at the steelworks. A new leadership team has been appointed to stabilise the business and turn it into a "commercially sustainable, low-carbon enterprise" (The Guardian).

Mofcom's response has been sharp and multifaceted. A spokesperson told Global Times that the UK "forcibly took control of British Steel and subsequently nationalised the company in the name of national security, seriously undermining Jingye's legitimate rights and interests." Mofcom described the nationalisation as a "severe blow to Chinese companies' confidence in investing in the UK" and called on the UK government to abide by the China-UK bilateral investment treaty and to treat Chinese companies operating in the UK in a "fair and impartial manner." A bilateral investment treaty is an agreement between two countries that sets rules protecting investors from each country who operate in the other. China also stated it will "closely follow developments, support Chinese companies in safeguarding their rights through legal means, and take strong measures to firmly protect the interests of Chinese companies" (The Guardian; Euronews).

Mofcom had signalled its opposition well before the final transfer. The ministry published a spokesperson's remarks on its English-language website dated May 19, 2026, prompted by UK media reports that nationalisation was forthcoming. A Spanish-language Mofcom article similarly called on the UK to defend equity, impartiality, and non-discrimination. The English-language remarks are permanently archived at Mofcom's spokesperson remarks index, alongside separate entries on unrelated trade matters (Mofcom English; Mofcom Spanish).

The compensation question is where this dispute is most likely to crystallise into formal legal proceedings. The UK government plans to appoint an independent valuer to determine compensation to Jingye, partly to forestall legal action under international treaties. Jingye, for its part, has argued in UK accounts and on its WeChat social media account that British Steel was a valuable asset worthy of large compensation. The bilateral investment treaty between China and the UK provides mechanisms for investor-state dispute settlement, a process that allows a foreign investor to bring a claim directly against a host government. Mofcom's explicit invocation of the treaty suggests Beijing is laying the procedural groundwork for a claim (The Guardian).

Local political pressure in the UK has been equally insistent. North Lincolnshire Council's leader said on July 2, 2026, that the Scunthorpe site "needs a future, not perpetual uncertainty." On July 14, the council called on the government to work closely with British Steel to protect jobs and secure the future of steelmaking, and stated that the government must use its new powers to secure virgin steelmaking and build a "more ambitious industrial future" (North Lincolnshire Council; North Lincolnshire Council).

The UK government's steel strategy document references "direct action" taken to protect steel production at British Steel, effective immediately after July 2026 (UK Government Steel Strategy).

The broader context here is one of converging pressures: deindustrialisation risk, national security framing of critical supply chains, and the diplomatic friction that arises when a host state expropriates assets owned by a strategic rival's investors. The UK has framed this as an industrial-resilience necessity. China has framed it as an expropriation dressed in national-security language. Both framings carry weight, and the compensation valuation will be the first concrete test of whether the treaty framework can absorb the shock or whether this dispute migrates into formal arbitration.
