China Leads Global Clinical Trials: New World Leader in Research Output and Publications

China's ascent in the global biomedical landscape marks a pivotal shift, positioning the nation as the foremost hub for clinical trials and scientific publications. Recent data reveals that from January 2024 to June 2025, China accounted for 24% of all clinical trials registered through the World Health Organization's International Clinical Trials Registry Platform (ICTRP), surpassing India at 23% and eclipsing the longstanding dominance of the United States.70 This surge underscores decades of strategic investments exceeding billions of yuan, transforming biotechnology into a national priority akin to the electric vehicle revolution.

The momentum extends beyond trials to research output, where China published a staggering 878,300 papers in the Web of Science Core Collection in 2024 alone, a dramatic rise from just 26,200 in 2000.69 With research and development (R&D) expenditures topping 3.6 trillion yuan (approximately $520 billion) in 2024, up 8.3% from the previous year, China now leads not only in volume but increasingly in high-impact citations and quality metrics. This leadership is propelled by policy reforms, massive funding, and a vast network of universities and hospitals driving innovation.

Surpassing Milestones: WHO Data Confirms China's Clinical Trial Dominance

Clinical trials, defined as prospective biomedical or behavioral research studies on human participants designed to answer specific questions about interventions such as drugs, cells, or devices, have seen China claim the top spot. The WHO's ICTRP aggregates data from 17 primary registries worldwide, providing a comprehensive view. In the pivotal period of January 2024 to June 2025, China's 24% share marked the first time it overtook the US, which historically led with 20% of cumulative trials from 1999 to mid-2025 (197,090 studies).70

This isn't isolated to recent months; China's share of global commercial clinical trials has doubled since 2018, from 9% to about 20% today.71 In oncology, the figure is even more pronounced at 39% of new trial starts in 2024, up from a mere 5% a decade ago. Companies like Jiangsu Hengrui Pharmaceuticals have risen to become the world's top clinical trial sponsor, overtaking AstraZeneca in 2024. These trials span phases, with investigator-led studies accelerating early-phase work through streamlined approvals that cut timelines by 50-70% from discovery to investigational new drug (IND) applications.

Stakeholders highlight regulatory reforms since 2015, aligning China with international standards like Good Manufacturing Practice (GMP), making it attractive for multinational trials in oncology and immunology. The National Reimbursement Drug List further incentivizes participation by negotiating steep price discounts (average 63% in 2024) and expanding access via state insurance.

University Powerhouses Fueling the Research Engine

Chinese universities are at the heart of this boom, with institutions like Zhejiang University (ZJU) topping the 2025 CWTS Leiden Ranking for total research output with over 40,492 publications, dethroning Harvard University (third place) and claiming seven of the top ten spots alongside Shanghai Jiao Tong University (SJTU, second).50 In the Nature Index, the Chinese Academy of Sciences (CAS) dominates globally with a Share of 3,163.01 across 11,063 articles, while universities like University of Science and Technology of China (USTC) and ZJU rank prominently in Asia-Pacific.72

Top performers in clinical medicine include Fudan University, SJTU, Peking University, and Sun Yat-sen University, per U.S. News rankings. These campuses leverage vast hospital networks for rapid patient recruitment—China's population advantage enables diverse cohorts quickly. For instance, ZJU's biomedical engineering and clinical trial centers have pioneered multi-center studies, contributing to over 1,250 new drugs developed annually in 2024, rivaling the U.S.'s 1,440.71

Programs like the Thousand Talents Plan have repatriated overseas experts, seeding startups and university labs. USTC's FuSEP Summer Research program exemplifies training the next generation in cutting-edge trials.Discover research positions at these leading institutions.

Policy and Investment: The Architect of Success

China's 14th Five-Year Plan (2021-2025) and upcoming 15th Plan (2026-2030) prioritize self-reliance in science and technology, channeling funds into biotech clusters in Beijing, Shanghai, and Guangzhou. R&D intensity reached 2.68% of GDP in 2024, with state directives favoring domestic procurement. Reforms expedited IND reviews, while the 2023 patient-centered guidelines from the National Medical Products Administration emphasize ethical standards.

• Over 70-95% global supply of key APIs like ibuprofen.
• Patent filings under PCT surged from 119 (2010) to 1,900+ (2023).
• National Reimbursement Drug List updates in 2025 cover rare diseases and chronics.

Geopolitical tensions, like the U.S. Biosecure Act (2025), pose hurdles, yet China's domestic ecosystem thrives. Experts note this 'whole-of-nation' approach mobilizes resources rapidly but risks underemphasizing basic research.

Challenges: Quality, Integrity, and Global Scrutiny

Amid quantity, quality concerns persist. Retractions and paper mills prompted a 2025 crackdown, mandating integrity training. While citations rise, some fields lag in originality—40% of cell therapy trials (2021-2023) target known molecules. Geopolitics limits U.S.-China collaborations, down due to data security. Yet, partnerships with EU, Asia-Pacific, and Africa grow.

China addresses this via global norm adherence in trial registration and reporting. Balanced views from experts stress collaboration: isolation hampers diverse cohorts and standards.

Case Studies: Oncology and Beyond

Oncology exemplifies leadership: 39% new starts in 2024, driven by firms like Hengrui and university-hospital alliances. Peking University's cancer center trials integrate AI for precision medicine. In immunology, rapid recruitment via 1,000+ Grade III hospitals accelerates phase II/III.

Beyond, cell/gene therapies see China rivaling the West, with 50%+ CAR-T trials globally. Sun Yat-sen's tropical disease research leverages local epidemiology.

Global Implications: A Multipolar Science Landscape

China's rise diversifies pipelines—23% global drug candidates in 2025. Multinationals partner for access; e.g., Roche, AstraZeneca expand. For academics, opportunities abound in China's higher ed jobs. However, reciprocity in data sharing is key.

Future Outlook: 15th Plan and Beyond

The 2026-2030 Plan targets breakthroughs, equity, and TCM rigor. Projections: continued publication lead, trial share to 30%+. Universities like SJTU aim for top-10 global clinically. Challenges: mature markets, IP trust.
