European Union officials are facing a diplomatic row after the United States sent an informal note expressing concern over the bloc's upcoming competitiveness fund, which will give preference to projects based in Europe.

The draft fund, part of the EU's broader industrial strategy, is designed to channel public money into strategic sectors such as advanced manufacturing, clean energy and digital technologies. According to the proposal, eligibility for certain calls could be conditioned on the applicant being established within the Union, a clause that the US sees as a barrier for its companies wishing to invest or supply to European projects.

In the US‑EU correspondence, Washington argued that the rule would force American investors to either forgo the funding or relocate production to the continent, thereby giving European firms an unfair advantage. The letter also warned that if the EU does not amend the preference clause, the United States could respond with reciprocal restrictions on European exporters.

European policymakers have stressed that the measure is not intended to exclude foreign capital outright. "American firms will still be able to invest in Europe," said a senior EU official, "but they may not qualify for the specific subsidies tied to the preference rule." The official added that the EU hopes the fund will stimulate domestic supply chains, reduce reliance on external sources and bolster strategic autonomy.

Potential work‑arounds and the cost of association

One avenue the US proposes is an association agreement that would allow American companies to participate on equal footing with European firms. Similar arrangements exist for Canada and the United Kingdom under Horizon Europe, the EU's research programme, where the partners contribute financially to gain access.

However, the United States has signalled it is unwilling to make a financial contribution. "We do not want to pay to be part of a fund that is essentially a subsidy for European competitors," the US note read. This puts the EU in a bind: either abandon the preference element, open the fund to US firms without a contribution, or risk a trade dispute.

Trade experts note that the EU could negotiate a broader package, linking the fund to concessions on other issues such as US tariffs on European steel. European governments have long called for the removal of those duties, and a quid‑pro‑quo arrangement could ease tensions.

Implications for European workers and supply chains

For European businesses, the preference rule could mean a reshaping of supply chains. A German entrepreneur developing a high‑tech project that relies on US‑made components might be compelled to source alternatives from within the EU to qualify for funding. While this could create new opportunities for local suppliers, it may also raise costs and delay timelines if suitable replacements are not readily available.

Unions across the continent have welcomed the prospect of stronger domestic industrial policy, arguing that it could safeguard jobs in strategic sectors and reduce the bloc's exposure to external shocks. Yet they also warn that any rise in production costs could be passed on to consumers, especially if firms are forced to replace cheaper imported inputs.

From a broader perspective, the dispute highlights a growing fault line between Paris and Berlin, two of the EU's biggest proponents of industrial sovereignty. Both capitals support a "Made in Europe" label, but they differ on how aggressively the EU should confront US trade pressure. France has signalled willingness to stand firm on the preference rule, while Germany appears more cautious, fearing retaliation that could hurt its export‑driven economy.

Analysts point out that the United States has a history of using trade measures to protect its own industries, and the current warning fits that pattern. "The US is a tough negotiator and will test the limits of the EU's resolve," said a senior trade commentator who has followed transatlantic talks for years.

Should the EU choose to maintain the current design of the fund, it will have to monitor US actions closely. Any retaliatory tariffs on European steel, automobiles or other goods could quickly affect employment in regions dependent on those sectors. Conversely, opening the fund to US participants without a contribution could dilute the policy's aim of fostering European‑led innovation.

At present, the EU's next steps remain unclear. The European Commission is expected to present the final text of the competitiveness fund later this year, after which member states will debate the balance between strategic autonomy and the risk of a trade clash with Washington. The outcome will shape not only the future of European industry but also the broader dynamics of EU‑US economic relations.
