China's Science Rise Tests Europe's Research Strength and Strategy

A new balance of scientific power

Chinese researchers led an estimated 45 percent of scientific papers produced jointly with US counterparts in 2023, up from around 30 percent in 2010. China also published close to 900,000 scientific articles, roughly three times its output in 2015. Together, those figures show a country taking a larger role in both producing research and directing international scientific work.

China has passed the United States in the Nature Index Research Leaders list, which measures contributions to 145 selected journals in health and the natural sciences. The gap widened in 2024. Chinese scientists now routinely lead collaborations with leading international partners, including American researchers, and their strength extends across chemistry, materials, physics and parts of the life sciences.

Europe faces a choice about how to respond: where to compete harder, where cooperation remains useful and where research needs protection. China's rise reaches beyond academic rankings. Scientific leadership helps determine which problems receive attention, where research methods and datasets originate, which standards become widely used and how quickly discoveries become commercial products.

As of November 7, 2025, the shift reflects a combination of sustained investment, a large scientific workforce and a deliberate effort to build leading institutions and technology industries. Europe retains considerable strengths, but differences between its national research systems make a common response difficult. Its task is to improve the quality and speed of research while preserving scientific openness and managing security risks.

The investment and talent behind China's expansion

China has increased public and private spending on research and development for two decades. That money supports large laboratories, national research programmes and an expanding range of scientific facilities. Research and development means the work of discovering new knowledge and turning it into useful technologies or products.

Chinese universities were projected to produce roughly 77,000 graduates with doctorates in science, technology, engineering and mathematics, known as STEM, in 2025. The comparable US projection was about 40,000. China's projected total was therefore almost twice the American figure. China also employs more researchers than the United States and the European Union combined.

China's growing workforce gives it more research teams, more facilities and broader coverage across scientific specialities. Scientists returning from leading programmes abroad, alongside researchers trained at home, now direct many institutes and large teams. Beijing has also encouraged strategic research partnerships and built networks that connect researchers across borders.

Companies in energy, transport, electronics and chemicals add another source of momentum. They bring practical problems to laboratories, provide funding and create routes for discoveries to reach production. Close connections between research and a rapidly developing industrial base have helped China advance in batteries, electric vehicles, clean energy manufacturing, telecommunications equipment and parts of advanced computing.

China's speed and coordination offer advantages in fields where large operations and disciplined engineering matter. Central direction can also constrain unconventional or risky ideas. The United States retains an advantage in areas that reward exploration driven by individual researchers and entrepreneurial science, although the gap is closing.

China's international network extends beyond established scientific powers. Programmes that train and sponsor researchers from Belt and Road partner countries have created lasting collaborations and a wider circle of scientific allies. Science diplomacy has connected laboratories from Asia to Europe and Africa, strengthening relationships through research and training.

Who leads international research teams?

A study using author contribution information across millions of papers found a steep rise in Chinese leadership of international collaborations over the past 25 years. Author contribution information describes the roles researchers played in a study, allowing the researchers conducting the analysis to infer who led the work.

Chinese researchers' estimated share of leadership in joint work with the United States rose by 15 percentage points between 2010 and 2023, from around 30 percent to about 45 percent. This is a change in responsibility within collaborations, alongside the growth in the number of papers China produces.

China had already reached equal leadership with the United Kingdom in collaborative research years earlier. Parity with the European Union was expected around 2025. If current trajectories continue, equal leadership with the United States in chemistry, materials and computer science is plausible by the late 2020s, with mathematics, physics and engineering following soon after. Those dates are projections based on the trends.

Leadership matters because the scientists directing a project help shape its questions, methods and use of data. As Chinese teams take that role more often, China gains influence over the starting points and practices of international research.

The main developments span several periods:

• 2010: Chinese researchers led around 30 percent of joint papers with US counterparts.
• 2015: China's publication output was roughly one third of the close to 900,000 articles recorded in 2023.
• 2019: The European Commission set out a strategy treating China as a partner, competitor and rival.
• 2023: Chinese researchers led an estimated 45 percent of joint papers with US counterparts.
• 2024: China's lead over the United States in the Nature Index widened.
• March 2025: Chinese Foreign Minister Wang Yi presented innovation, cooperation and multilateral institutions as central to China's international engagement.
• Late 2020s: China could reach equal leadership with the United States in several research fields if current trajectories continue.

What the journal rankings measure

The Nature Index uses a measure called Share to assign credit for weighted contributions to articles in its selected journals. Rather than simply counting every paper as a full contribution for every participating institution, the measure distributes credit among the institutions and countries involved.

China's adjusted Share rose in 2024 while the US figure fell, reversing the longstanding order between the two countries. Declines in chemistry and the physical sciences pulled down the American total. The United States continued to lead in biological sciences.

Publication volume and influence answer different questions. A total of close to 900,000 articles shows the scale of China's output. The Nature Index focuses on contributions to a selected group of high quality journals, helping show where influential research is being produced in large quantities. Its Share measure has limitations, but adds a view of research quality to the volume figures.

Chinese institutions have also climbed the institution rankings quickly. Seven of the top ten institutions in the Nature Index are now Chinese, while only a handful of Western institutions maintain positions at that level. China's rise therefore includes a concentration of research strength within individual organisations, as well as a larger national total.

Where science meets industrial competition

China's strongest research fields overlap with technologies central to economic and security competition. Materials and chemistry laboratories produce a growing share of influential work that feeds into batteries, solar cells and advanced alloys. Chinese energy technology companies can move new designs into large production operations at a pace few competitors can match.

Artificial intelligence presents a more mixed picture. The United States still leads in the strongest models and leading research, while China is catching up quickly and dominates patent applications. Models are the systems trained to perform tasks such as processing language or recognising patterns; patents concern claims to inventions.

Semiconductors remain an area shaped by restrictions on access to technology. Export controls have slowed China's access to the most advanced lithography equipment and powerful chips. Lithography is the process used to form tiny patterns on chips. Domestic engineering has nevertheless progressed in established chip manufacturing processes, chip design tools and packaging, which connects and protects chips within electronic systems.

Advanced industry assessments place China at or near the global frontier in electric vehicles and batteries. They also show strong positions in commercial nuclear technology, robotics, chemicals, displays and parts of artificial intelligence. Areas where China still trails tend to depend on highly specialised equipment, niche suppliers or established networks of companies and expertise.

That list is shrinking as domestic capacity grows. China's increasing ability to supply its own technology reduces reliance on foreign providers, while its production scale draws global supply chains toward Chinese standards and manufacturing systems. For Europe, research competition and industrial competition are closely connected.

Scientific ties under political pressure

The United States and China have both seen rising scientific nationalism, complicating joint projects through tighter visa screening and more compliance requirements at universities. US and European funders increasingly separate fields with limited security risks from sensitive areas that face restrictions or additional oversight.

China's policies also stress self reliance and resilience in science and technology. Its growing domestic strength has reduced dependence on Western collaborations in several areas, even as Chinese research output and influence continue to rise under pressure to separate scientific networks.

Washington and European capitals are developing approaches that preserve cooperation where benefits are clear while protecting research relevant to security. Transparency, reciprocity, intellectual property protections and regular security reviews are central to that balance. Reciprocity means partners should provide comparable access and accept comparable obligations.

Continued scientific exchange gives participants visibility into rapidly advancing fields and helps maintain research integrity. Shared standards also make it easier to compare results and build on discoveries. Fragmented standards can slow that work, giving governments and universities a reason to preserve suitable collaborations even as restrictions grow elsewhere.

Europe's strength is uneven

The Global Innovation Index for 2024 placed Switzerland, Sweden, the United States, Singapore and the United Kingdom at the top. Europe therefore continues to host many leading innovation economies. Its performance, however, varies considerably between countries.

A detailed analysis of publications in advanced technology and basic medical research found highly competitive work in the United Kingdom, the Netherlands and Switzerland. Germany, France, Italy and Spain performed below the global average for highly influential output in that analysis. The comparison concerns those research areas rather than every part of national scientific activity.

The European Research Council, or ERC, helps improve research quality across countries. Even among projects receiving ERC funding, however, work in Germany, France, Italy and Spain tended to receive fewer citations than projects in the United Kingdom, the Netherlands and Switzerland. Citations are references made to a study by later research and provide one measure of its influence.

Funding is only part of Europe's challenge. Research environments, university governance, incentives for taking risks and connections to industry all affect results. Several continental systems remain too centralised, have rigid career structures or place too much weight on publication quantity rather than quality. Europe's excellent research centres operate within a wider system whose conditions are uneven.

How Brussels is responding to China

The European Commission sharpened its approach to China in a strategic paper in 2019, setting out a relationship involving cooperation, competition and rivalry. That framework continues to guide selective cooperation and careful competition across policy areas.

The description in EU strategy documents from 2019, which set the policy framework for the relationship, was:

In EU strategy documents from 2019, China is described as a cooperation partner, an economic competitor, and a systemic rival.

Europe's policy tools now include screening foreign investments, controlling exports of sensitive technology, regulating foreign subsidies and using an instrument to counter economic coercion. Plans to secure critical raw materials address another source of vulnerability. Together, these measures serve the goal of open strategic autonomy: remaining open where possible while reducing exposure in areas affecting security or resilience.

EU member states are moving in the same direction at different speeds. Measures seek to protect critical infrastructure and research from unwanted technology transfers, while supporting domestic production in clean technology, digital industries and defence.

Coordination with the United States has tightened through transatlantic forums, but the EU also wants an independent voice on standards and market access. Agreement requires cooperation among 27 governments with different economic relationships with China. Those differences make a consistent approach harder to sustain.

China's position and the room for cooperation

Chinese Foreign Minister Wang Yi used a wide ranging press conference in March 2025 to present innovation and cooperation as central to China's engagement with the world. He described a preference for multilateral institutions, called for respect in competition with the United States and stressed predictable rules in trade and technology.

Chinese officials present stability, multilateralism and shared development as priorities while opposing restrictions on technology flows. Their position places international cooperation alongside China's drive to become more resilient and less dependent on foreign technology.

Practical openings remain in health research, climate and energy, disaster response, materials for sustainability and projects involving open data. Such work can provide shared benefits with limited security risk. Training programmes involving students from the Global South can also build goodwill and expand scientific capacity where it is needed.

Europe still has to assess individual exchanges carefully. Cooperation can strengthen China's industrial position in ways that later conflict with European interests. Clear incentives, reciprocal conditions and safeguards can reduce those risks while preserving useful work.

How Europe could improve its research system

Europe's response needs to raise quality and speed while retaining openness and its values. Greater university autonomy, more flexible hiring and rewards for originality and high quality work would address weaknesses in research environments. Expanding the ERC, which remains the leading model for discovery grants, is another proposed step.

The younger European Innovation Council could become a stronger bridge between laboratories and markets through patient investment and predictable funding as projects develop. Public procurement rules could give innovative young companies their first customer, supporting new solutions and giving those companies a reason to remain in Europe.

Talent policy is another part of the proposed response. A continental talent visa with faster residence procedures for researchers and their families could attract scientists facing political or administrative barriers elsewhere. Institutes operating across borders, with shared facilities and rotating leadership, could make better use of Europe's diversity.

Europe already has strengths in quantum research, fusion, particle physics and biomedical platforms. Connecting them to clusters of companies working on advanced technologies, with manufacturing capacity and support for expanding production, would help retain more of the economic value generated by discoveries.

Partnerships with the United States, the United Kingdom, Japan, South Korea, Canada, Australia and India could support work on semiconductors, AI safety, clean energy materials and biotechnology standards. Joint programmes can share expensive facilities, establish open standards and reduce exposure to bottlenecks in access to equipment or supplies.

Targeted cooperation with Chinese teams would remain part of this approach in fields with limited security risk, particularly where sharing data and reproducing results improve research. Clear intellectual property terms, verified affiliations and screening for possible civilian and military uses would be required.

Practical safeguards for scientific exchange

A proposed framework for engagement divides research by its risks and benefits, leaving suitable projects open while setting stricter conditions for sensitive work. Universities and companies need rules that are understandable, stable and matched to the technologies involved.

The following measures would put that approach into practice:

• Risk categories and approvals: Define low, medium and high risk fields, with matching reviews and independent panels that include security expertise for higher risk work.
• Transparency and reciprocity: Disclose funding sources, affiliations and terms for access to data, and require comparable disclosure from partners.
• Intellectual property agreements: Specify ownership of knowledge brought into a project and discoveries produced during it, alongside licensing rules and dispute resolution in neutral venues.
• Data protection and integrity: Require retention of data, records that allow work to be checked and tests of whether results can be reproduced. Share manuscripts before publication and computer code where possible in projects with limited risk.
• Research security reviews: Audit laboratories involved in higher risk collaborations annually and revise risk assessments as technology changes.
• Equipment and infrastructure controls: Track access to specialised tools and materials relevant to security, using trusted suppliers and service contracts.
• Safeguards for researcher mobility: Support whistleblowers, require declarations of conflicts of interest and provide research security training for visiting scholars.

These proposals combine scientific exchange with protection of critical knowledge. Europe's central challenge is to improve its own research and industrial capacity while making cooperation predictable enough for useful discoveries to continue.
