The High Representative’s Job: Steering EU Foreign Policy in a Multipolar World
The EU’s top diplomat is simultaneously one of the most powerful figures in Brussels and one of the least understood. Kaja Kallas, who became High Representative in 2024, speaks for 27 member states on the world stage — yet her authority depends entirely on whether those states can agree among themselves. For UK readers, this matters more than it might seem. Britain left the EU, but it did not leave Europe. From sanctions on Russia to trade deals with Mercosur, from Taiwan Strait tensions to defence procurement, the decisions made by the High Representative shape the strategic environment Britain operates in. If we want to read EU foreign policy signals correctly, we need to understand who is actually sending them.
What the High Representative Actually Does

The title sounds straightforward, but the role is a hybrid creation that confuses even seasoned Brussels watchers. The High Representative of the Union for Foreign Affairs and Security Policy wears two hats at once, and the tension between them defines the job.
The Dual Hat: Commission Vice-President and Council Chair
As a Vice-President of the European Commission, the High Representative sits inside the EU’s executive branch, overseeing external action portfolios and coordinating with commissioners responsible for trade, enlargement, and neighbourhood policy. As Chair of the Foreign Affairs Council, she presides over meetings of the 27 foreign ministers, setting agendas and steering debates. This dual mandate was designed to bridge the old divide between Commission-led economic diplomacy and member state-led political diplomacy. In practice, it means Kallas must serve two masters: the Commission president, who controls her institutional resources, and the member states, who control the political direction. When those two pull in different directions — as they often do on Israel, China, or defence spending — the High Representative has limited room to manoeuvre.
Running the European External Action Service
Underpinning the role is the European External Action Service (EEAS), established by the Lisbon Treaty in 2009. The EEAS functions as a kind of EU foreign ministry, staffed by diplomats seconded from member states as well as Commission officials. It runs around 140 EU delegations worldwide, effectively giving the Union diplomatic representation in most capitals. The High Representative leads the EEAS, appointing senior staff and shaping its priorities. This gives her a genuine institutional base — something earlier EU foreign policy figures lacked. But the EEAS remains dependent on member states for personnel and political cover. When national capitals bypass Brussels and deal directly with Washington, Beijing, or Riyadh, the EEAS can only observe.
Strategic Autonomy: Rhetoric vs Reality
Few phrases in EU vocabulary are invoked more often — or defined less precisely — than “strategic autonomy.” For the High Representative, it captures a genuine dilemma: how does the EU build capacity to act independently while maintaining the transatlantic alliance that has underpinned European security since 1949?
The Strategic Compass and Defence Integration
The 2022 Strategic Compass set EU defence goals, including a rapid deployment capacity of up to 5,000 troops, expanded crisis management tools, and closer defence industrial cooperation. It was drafted in the shadow of Russia’s full-scale invasion of Ukraine, which exposed how dependent European militaries remain on American logistics, intelligence, and airlift. The High Representative is tasked with turning the Compass from a document into capability. Progress has been uneven. Joint procurement remains politically sensitive because it touches national defence industries and sovereignty. France pushes hardest for European solutions; Poland and the Baltics prioritise buying American kit because they trust it more and need it faster.
Tensions with NATO and Washington
NATO and the EU are not rivals in theory, but they compete for the same scarce resources and political attention. The High Representative must coordinate with NATO’s Secretary General while avoiding the impression that EU defence efforts duplicate or undermine the alliance. Washington watches closely. When Brussels talks about strategic autonomy, American policymakers hear a potential drift away from NATO. When the High Representative talks about burden-sharing, European capitals hear pressure to spend more. Balancing these expectations is a permanent exercise in ambiguity — and it is one reason the role attracts criticism from both Atlanticists and Europeanists.
Trade Policy: The High Representative’s Quiet Power
Trade is where EU foreign policy meets hard economic interest. The Commission’s trade department leads negotiations, but the High Representative shapes the political framing and links trade deals to broader geopolitical goals. This quiet power is often underestimated.
EU–Mercosur and the Green Deal Clash
EU–Mercosur trade talks resumed in 2023 after years of stalemate, with both sides pushing to conclude an agreement that would create one of the world’s largest free trade areas. But the deal collides with the EU’s Green Deal agenda. French farmers oppose Brazilian agricultural imports produced under different environmental standards. The High Representative must argue that the agreement advances European influence in Latin America — countering Chinese inroads — while managing domestic backlash. It is a case study in how trade policy has become foreign policy, and why the High Representative cannot stay out of it.
What Post-Brexit UK Trade Means for Brussels
Brexit removed the UK from EU trade policymaking, but it did not remove British trade from European calculations. The UK’s independent trade deals — with Australia, Japan, and the CPTPP — create competitive dynamics the EU must factor in. When London negotiates faster or offers more liberal terms, Brussels feels pressure to respond. The High Representative’s office monitors these developments closely, because UK trade strategy influences everything from EU–US relations to EU–India talks. For Britain, understanding this dynamic is essential: EU trade policy is not made in a vacuum, and UK moves shape it.
EU–Asia Relations: The High Representative’s Toughest Test
Nowhere is the High Representative’s job more difficult than in Asia, where economic interdependence, security tensions, and diverging member state interests collide.
De-risking from China Without Decoupling
The EU’s de-risking agenda aims to reduce critical dependencies on China — in semiconductors, rare earths, pharmaceuticals — without severing trade ties altogether. The High Representative must sell this nuanced position to member states with wildly different exposures. Germany’s car industry depends on Chinese markets. Lithuania faced Chinese economic coercion after opening a Taiwan representative office. Greece and Hungary welcome Chinese investment. Holding a common line requires constant diplomacy.
Taiwan, the Indo-Pacific, and UK Alignment
The UK’s AUKUS pact with Australia and the US shapes EU–Asia calculations. AUKUS signals that Anglo-American security cooperation in the Indo-Pacific is deepening, and EU member states must decide whether to align, hedge, or stay out. The High Representative has pushed for a more visible EU presence in the Indo-Pacific, including naval coordination and port infrastructure investment. But sending European ships to the South China Sea risks escalation with Beijing and divides member states. On Taiwan, the EU walks a careful line: no formal recognition, but growing concern about Chinese military pressure. UK alignment with the US on Taiwan affects how Brussels calibrates its own stance — another reminder that British decisions ripple through EU strategy.
Why the Job Is Impossible (and Why It Still Matters)
We should be honest: the High Representative’s role is structurally constrained in ways that make full success unlikely. Yet it remains indispensable to the EU’s global Europe ambitions.
Unanimity, Vetoes, and Member State Ego
Most major foreign policy decisions require unanimity among the 27. A single member state can block sanctions, delay statements, or water down commitments. Hungary has repeatedly used this leverage on Russia policy. Cyprus blocks action on Turkey. National capitals guard their foreign ministries jealously and resist Brussels encroachment. The High Representative has no army, no intelligence service of her own, and no power to compel. She can propose, persuade, and coordinate — but she cannot command.
The Case for a Stronger High Representative
Despite these constraints, the case for strengthening the role is compelling. In a multipolar world, the EU needs a single voice that can engage China, the US, India, and the Global South without 27 separate bilateral channels. The alternative — pure intergovernmentalism — produces paralysis and irrelevance. A stronger High Representative, backed by qualified majority voting on some foreign policy issues, would give Europe more weight. But that requires member states to surrender control, which few are willing to do. The job will remain impossible precisely because it is designed that way.
Key Takeaways
- The High Representative wears two hats — Commission Vice-President and Chair of the Foreign Affairs Council — which creates constant tension between institutional and member state interests.
- Strategic autonomy remains more rhetoric than reality, as EU defence integration clashes with NATO dependencies and national sovereignty concerns.
- Trade policy is where the High Representative exercises quiet but significant geopolitical influence, from Mercosur to post-Brexit UK dynamics.
- EU–Asia relations represent the toughest test, balancing de-risking from China with member states’ divergent economic exposures.
- Unanimity requirements and national vetoes structurally constrain the role, yet a stronger High Representative remains essential for EU relevance in a multipolar world.
FAQ
Who is the current EU High Representative?
Kaja Kallas, former Prime Minister of Estonia, became High Representative in 2024. She succeeded Josep Borrell and took office amid heightened tensions with Russia and ongoing debates over EU strategic autonomy.
What is the difference between the High Representative and the European Commission President?
The Commission President leads the EU’s executive branch and sets overall priorities. The High Representative is a Vice-President of the Commission responsible specifically for foreign affairs and security policy, while also chairing the Foreign Affairs Council of member state ministers.
Does the High Representative control EU trade policy?
Not directly. Trade negotiations are led by the Commission’s trade department. However, the High Representative influences the political context, links trade to geopolitical strategy, and coordinates with member states on ratification and implementation.
Why does the High Representative matter for the UK?
Because EU foreign and trade policy directly affects Britain’s strategic environment. Sanctions regimes, trade agreements, defence cooperation, and positions on China and Russia all shape the conditions the UK operates in — even outside the bloc.
What is the EEAS and why was it created?
The European External Action Service was established by the Lisbon Treaty in 2009 to give the EU a unified diplomatic corps. It supports the High Representative, runs EU delegations worldwide, and coordinates foreign policy implementation.
For Britain, reading EU foreign policy correctly means understanding the High Representative’s constraints as well as her powers. Kallas speaks for Europe — but only when Europe lets her. That gap between mandate and reality is where the real story lies, and it is one we will keep tracking at global-europe.org.
