Global research networks

International collaboration is how research on shared risks is done, and it is governed by agreements between funders, institutions and states, by export control and research security rules, and by the terms partners are able to negotiate. This page sets out how authorised international networks are built and kept open, how security and openness are balanced, and which institutions decide what can be shared, with whom and under what conditions.

01In brief

The short answer.

International research collaboration is the joint work of researchers and institutions across borders, governed by agreements between funders, institutions and states and by research security and export control rules. Open collaboration and security due diligence must be balanced case by case, and the decisions rest with institutions and governments.

04The question

Global research networks: how the risk develops.

Authorized international collaborations. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Openness meets security

Concerns over foreign interference, dual-use knowledge and data protection bring new screening, export control and disclosure rules. Applied broadly, they can chill legitimate cooperation and fall unevenly on researchers by nationality.

Mechanism

Geopolitics reroutes ties

Sanctions, conflict and diplomatic shifts suspend agreements and close data flows. Networks reorganise around remaining partners, and shared monitoring of global risks loses coverage where tension is highest.

Mechanism

Capacity is uneven

Partners with less funding, infrastructure or legal support enter agreements on weaker terms. Unless agreements build capacity, collaboration reproduces dependence, and evidence from some regions stays thin.

Mechanism

Mobility is constrained

Visa rules, travel costs and recognition of qualifications shape who can take part. Restrictions on mobility reduce the exchange that sustains trust between research communities across borders.

05Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Research securityMeasures that protect research from misappropriation, interference and undisclosed foreign influence while keeping it open where it can be.
Export controlsLaws that restrict the transfer of listed goods, software and technology, including some research knowledge, to other countries or persons.
Science and technology cooperation agreementA treaty-level agreement between governments that sets a framework for joint research, mobility and the handling of intellectual property.
06Indicators

What is measured, and how well.

Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.

From sources to decisions.

The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

10Core questions

What experts ask about international research networks.

  • Which approvals does each partner need, and are they in place before work begins?
  • How can data move across borders lawfully and securely?
  • How is research security balanced with openness?
  • Do networks include researchers from all affected regions, not only those with the most resources?
  • How are results shared with the communities and countries where data was collected?
  • What happens to shared data and joint outputs if a partner must withdraw because of a change in law or policy?
11Mechanisms

What shapes international collaboration.

Authorization

Rules of each partner

Ethics approvals, institutional agreements, data protection and export controls apply in every jurisdiction involved.

Openness

Shared knowledge

Open exchange speeds discovery, especially for global risks such as pandemics and climate change.

Security

Research security

Governments increasingly review collaborations in sensitive areas, which can slow or restrict exchange.

12Methods and limits

Practices for authorized networks.

Authorized collaboration has a practical toolkit, refined over decades of international science. Its instruments reduce friction but cannot remove the need for each partner to secure its own approvals.

  1. 01

    Framework agreements

    Institutional agreements that set terms for collaboration. Limits: can take a long time to negotiate.

  2. 02

    Federated data analysis

    Analysing data where it sits, sharing only results. Limits: technically demanding and limited for some analyses.

  3. 03

    Due diligence

    Checking partners, funding and applicable controls. Limits: requirements vary and change.

  4. 04

    Comparative policy review

    Comparing research policies across countries, using policy science. Limits: rapid policy change.

14Questions

Questions and answers.

What is research security?
Measures that protect research from misappropriation, interference and misuse while keeping it as open as possible. They include disclosure rules, due diligence on partners and controls on sensitive technologies.
Does research security conflict with open science?
It can, which is why many frameworks describe research as open by default and protected where necessary. Governments and institutions set the balance for each field and partner.
What does authorised mean here?
That a collaboration operates under the agreements, permissions and controls required by the institutions and states involved. Research Nexus does not grant or verify those authorisations.
Does joining a Research Nexus dialogue create a research partnership?
No. Dialogue participation creates no partnership, agreement or obligation.
Who checks that a collaboration is authorized?
Each partner institution and the relevant authorities. Research Nexus convenes only around collaborations that participants confirm are authorized.
Why does research security matter?
Some research has dual uses or involves sensitive data. Governments set rules to protect it, and collaborations must respect them.
Can researchers from any country take part in dialogue?
Dialogue is open in principle to qualified researchers from any region, subject to applicable law. Participation from under-represented regions is actively sought.
