Science diplomacy gives countries practical ways to use scientific evidence in foreign policy, sustain research cooperation, and keep channels open when political relations are strained. It matters more—not less—as governments navigate geopolitical rivalry, research-security concerns, and competition over technology and data. But it is a tool for cooperation, not a guarantee of peace or trust.
What science diplomacy means
Science diplomacy describes the connections between science and international relations. The European Commission’s definition encompasses direct and indirect uses of science, scientific evidence, and scientific cooperation in support of diplomatic objectives, as well as diplomacy that helps science progress. The Commission’s overview presents it as a broad practice rather than a single program or institution.

- Science informing diplomacy: scientific evidence, advice, or foresight can help officials understand international problems and shape policy.
- Diplomacy supporting science: diplomatic engagement can help researchers cooperate across borders and sustain access to shared expertise or resources.
- Science cooperation serving both: joint research can advance knowledge while also creating working relationships between institutions and countries.
These functions can overlap. Their value depends on the issue, the participants, and whether cooperation can be maintained in practice.
Why it is needed in a fragmenting world
Shared problems cross borders
Many policy challenges require knowledge and coordination across countries. Scientific advice can help diplomats assess evidence; cooperation can let researchers exchange methods, knowledge, and resources. The European Commission’s 2016 communication, quoted on its current science diplomacy page, argued that international research cooperation, common standards, scientific exchange and mobility, shared resources, and scientific advice to diplomats should support governance and policy-making and help build mutual understanding and trust. That is an account of intended benefits, not evidence that these outcomes reliably follow.

Political strain can make scientific channels more valuable—and more difficult
When official relationships are tense, research networks and technical discussions may offer areas for continued practical engagement. Yet scientific ties do not sit outside geopolitics: governments also weigh research security, strategic interests, and control of technology and data. The policy challenge is therefore not simply to maximize openness, but to decide where cooperation is valuable and what safeguards are appropriate.
Scientific input can strengthen international decisions
Foreign policy often involves complex, fast-changing issues. Scientific advice and foresight can help decision-makers identify risks, understand uncertainty, and consider future scenarios. They inform political choices; they do not replace diplomacy, public accountability, or decisions about competing national interests.

How governments are approaching the challenge
The European Union’s framework
The European Commission says it adopted its proposal for an EU framework on 27 February 2026; the Council adopted a recommendation on the framework on 29 May 2026. It is an EU recommendation, not a binding global framework. Its stated aims include supporting European values and strategic interests, strengthening open and secure scientific cooperation, improving trust in science and the use of foresight and scientific advice, and contributing to peace, human rights, multilateralism, and management of global commons. It also seeks coordination and practical guidance for member states and stakeholders. These are aims, not demonstrated results.
Recommended Free Tools
The process behind the recommendation brought together 130 science and diplomacy experts, according to the Commission. Five working groups, established in 2024 and co-chaired by a scientist and a diplomat, considered geopolitics in a fragmented, multipolar world; evidence and foresight for resilient diplomacy; science diplomacy in delegations and embassies; capacity-building; and shared definitions, mission, vision, and values. Their February 2025 expert report informed the 2026 recommendation.

UNESCO’s global dialogue
UNESCO held its Global Ministerial Dialogue on Science Diplomacy at its Paris headquarters on 25–26 March 2025, under the International Decade of Sciences for Sustainable Development. UNESCO’s event page reports around a thousand participants, including 60 high-level national representatives. Discussions addressed open science and research security, emerging technologies, shared scientific and natural resources, and science in times of crisis. The dialogue aimed to advance discussion of a new global framework; it did not itself establish a binding framework.
The ministerial statement called for stronger dialogue between science and diplomacy and for science diplomacy to respond to complex challenges. It is a collective political declaration, not an independently tested finding about effectiveness. The participation figures describe the scale of the event, not its impact.

Capacity-building beyond Europe
In June 2026, UNESCO reported that the three-year Consolidating European Science Diplomacy (CUSP) project had launched on 1 June. Coordinated by the Zentrum für Soziale Innovation, it brings together 11 organisations and responds to the 2025 European expert report and the May 2026 Council recommendation. UNESCO’s project update describes planned regional policy dialogues, global mapping and knowledge exchange, and training and capacity-building with TWAS. The plans specifically attend to perspectives from Africa, Latin America and the Caribbean, Asia and the Pacific, and Arab States. They are planned activities, not completed results.

Science diplomacy involves choices that cannot be reduced to “open” or “closed.” The EU and UNESCO policy discussions point to several practical tensions:

- Openness and security: broad exchange can support research, but governments also assess risks tied to sensitive research, technology, and data.
- Scientific autonomy and foreign-policy priorities: research has its own aims and norms, while governments may seek to align cooperation with strategic interests.
- National, regional, and multilateral action: bilateral or regional engagement may be practical for some issues; global challenges can call for broader coordination.
- Immediate goals and long-term relationships: short-term strategic objectives may not align neatly with sustained cooperation or capacity-building.
- Representation: whose expertise, needs, and interests shape agendas matters, especially when initiatives seek participation beyond Europe.
Those choices call for context-specific policies. The cited initiatives support coordination and dialogue, but they do not establish one universal formula for balancing these interests.
What science diplomacy can—and cannot—show
Official initiatives describe science diplomacy as a way to support evidence-informed policy, cooperation, and dialogue. The available figures—UNESCO’s event attendance, the EU consultation’s 130 experts, and CUSP’s 11 organisations—measure participation and project composition. They do not demonstrate that science diplomacy caused a reduction in conflict, rebuilt trust, or improved diplomatic outcomes. The cited official sources provide no named statistic establishing such a causal impact.
That distinction does not make the approach irrelevant. It means its value should be judged through specific activities and outcomes rather than attendance totals or broad promises: whether useful scientific advice reaches decision-makers, whether secure cooperation can continue, and whether participants are meaningfully represented. The policies establish intentions and structures; the results require evaluation.
