What Science Diplomacy Is and Why It Looks Different Now
Understanding science diplomacy today: Part 1 of a five-part introductory series.

Science diplomacy is how nations use research, knowledge, and technical skills to work together. It has helped shape world politics for a long time, from nuclear weapon rules and environmental laws to health and space projects. It isn't new, but the world around it has changed.
Working together on science is now much harder and more closely watched by governments. Competition between nations has grown. Technology is moving faster than our ability to make rules for it. Issues like protecting research, controlling supply chains, and the gap between rich and poor nations are now constant problems. Science is no longer seen as a "neutral" space. Instead, it is deeply tied to national security, making money, and gaining political power.
An Old Way of Working in a New World
Science diplomacy has been around for a long time. Even during the Cold War, nations worked together on science in very sensitive areas.
For example:
Nuclear Rules — Agreements to limit weapons depended on technology to prove everyone was following the rules.
Antarctica — The treaty to keep Antarctica peaceful relied on nations sharing their research.
Space & Research — Sometimes, sharing science was the only way for nations to talk when their governments were fighting.
In these cases, science was both a tool and a symbol. It provided facts, helped verify agreements, and kept a conversation going between nations with different ideas. Even when trust was low, this cooperation continued in small, careful ways.
After the Cold War ended and the world became more connected, things changed. Scientific teamwork grew quickly. Big global projects started happening more often. Sharing data and working across borders became the normal way of doing things. People became more hopeful, believing that shared knowledge would naturally lead to better relationships and solve global problems.
That optimism changed how people thought about science and diplomacy.
From Openness to New Rules
In 2010, the American Association for the Advancement of Science and the Royal Society created a guide. It described science diplomacy as a way to use science to help nations make decisions, a way for diplomacy to help scientists work together, and a way for research to improve how nations get along. The guide was useful, but it reflected a time when nations had more confidence in global organizations and were happy to share research openly.
Since then, the world has changed, prompting a need to update the guide in 2025.
Several big pressures have forced science diplomacy to work differently in real life. The COVID-19 pandemic showed that nations can struggle to share data and medical supplies when things get difficult. At the same time, breakthroughs in AI and other technologies can be used for both normal life and for military power, which makes it hard to separate everyday research from national security.
Governments in nations like the United States and the U.K. now use travel restrictions and trade rules to control research that used to be shared freely. Science diplomacy has not stopped because of these pressures, but it has become much more careful. Nations are now much more selective about who they work with and what they share.
Science as a Source of Power
Today, choices about research money, technical rules, data management, and new inventions have major diplomatic effects. Technical decisions now influence trade, development, security, and how global rules are made.
This is easy to see in the real world. During the pandemic, arguments over sharing data, getting vaccines, and following health advice became major diplomatic fights. These disputes were shaped as much by trust and power as they were by medical facts. More recently, debates over AI rules, technology controls, and research security have moved scientific teamwork into the center of government strategy.
In this world, science diplomacy is less about building trust and more about managing how nations depend on each other. Cooperation still happens, but it is more selective. Organizations are watched much more closely by politicians. Scientific teamwork is often kept alive not to fix every conflict, but to stop existing problems from getting worse.
A Broader Way of Working, With Limits
Today, science diplomacy is much more than just official meetings between governments. It happens through international groups, networks of scientists, advisory teams, and even informal conversations. It involves setting global rules, coordinating during emergencies, managing risks, and helping different nations build the skills they need to succeed.
Scientific knowledge now helps decide how we view global problems and which solutions we choose to trust. At the same time, the goals of a nation’s foreign policy often determine what research gets funded and which scientists work together. This relationship goes both ways: science influences politics, and politics influences science.
Because of this, science diplomacy is not a perfect system or a promise that things will work out. Instead, it is a way of working that is constantly shaped by power, government institutions, and political limits.
What This Series Examines
The way science diplomacy works today is the result of past choices. These were choices about how science should relate to power, how much research should be shared openly, and where nations could work together.
Those decisions were made during a different time in history that has since changed. By looking at how things have evolved, we can see more clearly why science diplomacy works the way it does now and why it is facing more challenges than before.
