The European Union is preparing to impose binding requirements on companies operating within its borders to diversify their sources of critical components, in a move that would fundamentally restructure supply chains across key industrial sectors. According to sources cited by the Financial Times, the draft rules – still in their early stages – would compel firms to procure essential inputs from at least three different suppliers, with no single source accounting for more than 40 percent of any final product's components. The proposal is due to be presented to the European Commission on 29 May for discussion on the bloc's relations with China. The sectors likely to be affected include chemicals and industrial machinery, both heavily dependent on Chinese imports.

The initiative, driven by EU Trade Commissioner Maroš Šefčovič, reflects growing unease in Brussels about Europe's strategic vulnerability to a single supplier. Viewed from Washington, such measures align with parallel efforts by the United States to reduce reliance on Chinese manufacturing. However, analysts in London note that the EU's approach is more explicitly regulatory, targeting corporate procurement practices rather than tariff barriers. The plan also echoes France's recent calls for greater 'economic sovereignty' though it stops short of full decoupling.

The regulatory push comes as Chinese companies face mounting compliance challenges in Europe, often exacerbated by their own cost-cutting habits. A recent case in Belgium illustrates the problem: plans for a large battery factory – which would have created 2,000 jobs – stalled because the Chinese investor avoided hiring a law firm for a proper due diligence report, according to Xiufang Tu, a partner at the Brussels-based Daldewolf law firm. Such incidents are becoming more frequent as Chinese firms expand into the EU's stricter regulatory environment, and the new diversification rules would raise the bar further.

Looking ahead, the EU's supplier diversification rules represent a significant step in the bloc's evolving strategy to manage its economic relationship with China. If implemented, they will force European companies to overhaul their procurement systems, while Chinese firms seeking to enter the European market will need to invest heavily in legal and compliance infrastructure. The coming months will test both the EU's regulatory resolve and the adaptability of Chinese businesses, as the geopolitical dimensions of trade policy increasingly dictate the rules of engagement.
