The National Natural Science Foundation of China (NSFC) is China’s principal state funding agency for basic and applied basic research, awarding competitive, peer-reviewed grants across the natural sciences, engineering, life sciences, and interdisciplinary fields. This page is an orientation for researchers outside mainland China — international collaborators, prospective co-authors on NSFC-funded work, and researchers of Chinese heritage based abroad — not a step-by-step application manual for domestic Chinese applicants navigating the system day to day.
Not the same organization as the (US) National Science Foundation. “NSFC” and “NSF” are easy to conflate because the names are nearly parallel translations of each other, but they are entirely separate national agencies with no organizational relationship: NSFC is China’s foundation (nsfc.gov.cn), and NSF is the United States’ foundation. If a co-author, citation, or grant acknowledgment says simply “NSF,” confirm which country’s agency is actually meant before assuming it refers to either one.
What Is the National Natural Science Foundation of China?
NSFC is a state-funded public agency under China’s State Council system that administers competitive, peer-reviewed funding for basic research and applied basic research, primarily at Chinese universities and research institutes. It is one of the largest single channels of competitive basic-research funding in China by both proposal volume and total award value. According to NSFC’s own reporting, in 2023 the foundation received roughly 318,000 proposals from 2,404 host institutions and approved about 52,500 awards, with total funding equivalent to roughly 31.9 billion yuan (RMB) — figures NSFC publishes annually and which change from year to year, so treat any specific number as a snapshot rather than a current figure. NSFC has also been the subject of periodic Chinese government institutional reform (most recently in 2023), which has adjusted aspects of its administrative structure without changing its core role as the country’s main basic-research grant-making body.
Major Funding Program Categories
NSFC organizes its funding into a multi-tiered set of program categories. The list below reflects NSFC’s own program structure as published in its annual “Guide to Programs” and annual reporting; exact eligibility, funding levels, and deadlines are set and revised year to year, so treat this as a map of the landscape rather than a fixed rulebook.
General Program
NSFC’s largest single category by award count, supporting individual investigator-led basic research projects across all funded disciplines. In 2023, NSFC approved over 20,000 General Program awards — by far its highest-volume program.
Young Scientists Fund
A dedicated early-career track (sometimes listed with a related “Fund for Less Developed Regions” track), intended to build a pipeline of early-career investigators. NSFC approved nearly 23,000 Young Scientists Fund awards in 2023.
Key Program and Major Program
Key Program awards fund larger-scale, more focused projects than the General Program, typically aligned with priority research directions. Major Program awards are larger still, generally organized as coordinated, multi-team efforts around a strategic scientific objective.
Major Research Plans
Multi-year, thematically organized funding initiatives built around a specific strategic scientific area (for example, frontier technology areas the Chinese government has identified as priorities), typically encompassing multiple individual projects funded over several years under a shared plan.
Original Exploratory Program
A smaller, higher-risk category intended specifically to support non-consensus, high-originality research ideas that might not fare well under conventional peer review criteria.
Joint Funds
Co-funded programs in which NSFC pools resources with Chinese provincial governments, state-owned enterprises, or industry sectors to fund research aligned with regional or sectoral priorities. As of NSFC’s 2023 reporting, 29 provincial-level regions and 12 state-owned enterprises participated in Joint Funds for regional or corporate innovation, alongside ten industry-sector joint funds.
Programs for International and Overseas-Based Researchers
Most NSFC funding is structurally similar to other major national funders: awarded to a Chinese host institution, typically with a Chinese-based principal investigator of record. A smaller set of programs, however, is built specifically around researchers based outside mainland China or researchers without Chinese citizenship. These are the ones most relevant to this page’s audience.
Research Fund for International Scientists (RFIS)
RFIS is NSFC’s dedicated funding mechanism for international scientists of any nationality who are prepared to conduct basic or applied basic research at a Chinese mainland host institution. Per NSFC’s own program guidelines, RFIS has three sub-types, each with its own doctoral-recency and seniority requirements and its own funding level:
- RFIS-I (International Young Scientists) — for researchers with a doctoral degree obtained within roughly the past 6 years; direct-cost funding of 200,000 RMB per year.
- RFIS-II (International Excellent Young Scientists) — for researchers with a doctoral degree obtained within roughly the past 15 years and a senior academic title (associate professor level or above, or equivalent); direct-cost funding of 400,000 RMB per year.
- RFIS-III (International Senior Scientists) — for senior researchers with a senior academic title and an established international research record; direct-cost funding of 800,000 RMB per year.
A key structural point for anyone considering RFIS: it funds in-China research, not remote or armchair collaboration. NSFC’s published guidelines require the applicant to be affiliated with a China-mainland host institution registered with NSFC and to commit to working at that host institution for no less than nine months per calendar year during the project. Applicants are limited to one RFIS sub-type application per year and can only be awarded each sub-type once. Confirm current-year figures, eligibility windows, and application codes directly against NSFC’s own published call guidelines before applying, since specific thresholds (such as the doctoral-degree recency window) are defined relative to the current application year and shift accordingly.
Excellent Young Scientists Fund (Overseas)
This is a separate, talent-recruitment-oriented program aimed at outstanding young scholars currently based outside China — commonly discussed in the context of Chinese-diaspora researchers, though eligibility is not limited strictly by citizenship or ethnicity in every published call. As with RFIS, the underlying premise is relocation: the program is structured to bring an overseas-based scholar to work at a Chinese host institution, rather than to fund a standalone project carried out entirely abroad. Age/doctoral-recency thresholds and other criteria are set per application cycle in the program’s own call guidelines and change from year to year, so this page deliberately does not state a fixed eligibility rule.
International (Regional) Cooperation and Exchange Programs
NSFC also jointly funds research with partner funding agencies in other countries and regions, rather than funding an individual foreign researcher directly. Per NSFC’s own 2023 reporting, the foundation jointly funded 654 projects under International (Regional) Cooperation and Exchange Programs with partner agencies in countries including the United States and Germany, as well as with Hong Kong and Macau, including a subset of projects under its Sustainable Development International Cooperation Program. In practice, an international researcher typically accesses this route as a named collaborator or co-investigator on a joint application led by a Chinese PI and matched by their own national funder, rather than by applying to NSFC alone. Specific active partner agencies and joint call structures change over time and should be confirmed on NSFC’s international cooperation pages, and, where relevant, with your own national funding agency’s international-cooperation office.
How International Researchers Typically Engage with NSFC-Funded Research
- As a named collaborator or co-investigator on a project led by an NSFC-funded Chinese PI, including through International (Regional) Cooperation and Exchange Programs jointly funded with a researcher’s own national agency.
- As a direct RFIS grantee, relocating to a Chinese host institution for the funded project period under one of the three RFIS sub-types.
- As an Excellent Young Scientists Fund (Overseas) awardee, typically as part of a longer-term move or return to a Chinese host institution rather than a short project.
- As a co-author or research partner on published work arising from an NSFC-funded project, without being an NSFC grantee at all — the most common way most international researchers actually interact with NSFC funding in practice.
Research Security and Compliance Considerations
Researchers and research administrators outside China who are considering or already engaged in NSFC-linked collaboration should be aware that disclosure of foreign funding sources, foreign affiliations, and foreign “current and pending support” — including NSFC grants, host-institution appointments, and formal collaboration agreements — is a compliance area that has drawn increased scrutiny from US and other national funders and institutions in recent years. This is a general disclosure-and-compliance matter, not specific to NSFC as an agency, but it applies squarely to NSFC-linked work given the current research-security climate around US–China scientific collaboration. See CASRAI’s guide to US–China research collaboration: research security and compliance concerns for a fuller treatment, and check your home institution’s disclosure, foreign travel security, and export-control policies (see export control (EAR/ITAR) and international research collaboration) before formalizing any NSFC-linked appointment, host-institution agreement, or joint proposal.
How to Find Current Programs, Deadlines, and Funding Amounts
NSFC’s official English-language site, nsfc.gov.cn/english, is the authoritative source for current program listings, funding amounts, application codes, and deadlines, including its annually updated “Guide to Programs” publication and dedicated International Cooperation section covering RFIS and partner-agency programs. Because NSFC revises program structure, funding levels, and eligibility windows on an annual cycle, this guide intentionally avoids treating any single year’s figures as permanently fixed — always confirm current-cycle details on NSFC’s own site, and, where a Chinese host institution is involved, with that institution’s international office, before planning an application or collaboration.
Frequently Asked Questions
Is NSFC the same as the (US) National Science Foundation (NSF)?
No. NSFC (National Natural Science Foundation of China) and NSF (the U.S. National Science Foundation) are separate national agencies of separate countries, with no organizational relationship, despite the near-parallel names.
Can a researcher based outside China apply directly to NSFC?
In most cases funding is awarded to a Chinese host institution with a China-based PI of record. The direct exception is the Research Fund for International Scientists (RFIS), which funds international scientists of any nationality directly — but it requires relocating to a China-mainland host institution and committing to work there at least nine months per year during the project; it is not a mechanism for funding research carried out entirely abroad.
What is the Research Fund for International Scientists (RFIS)?
RFIS is NSFC’s dedicated funding track for foreign-national scientists conducting basic or applied basic research at a Chinese mainland host institution, split into three sub-types by career stage and seniority (RFIS-I, II, and III), each with its own doctoral-recency/seniority criteria and annual direct-cost funding level.
What is the Excellent Young Scientists Fund (Overseas)?
It is a talent-recruitment-oriented NSFC program aimed at outstanding young scholars currently working outside China, structured to bring them to a Chinese host institution rather than to fund a project carried out entirely abroad. It is frequently discussed in the context of Chinese-diaspora researchers, though published eligibility criteria are not limited strictly by citizenship in every call.
Can international researchers collaborate with NSFC-funded projects without becoming NSFC grantees themselves?
Yes — this is the most common form of international engagement in practice. Researchers based abroad frequently participate as named collaborators or co-investigators on a Chinese PI’s NSFC-funded project, or as co-authors on the resulting published work, without ever holding an NSFC grant themselves. Some of this collaboration is formalized through NSFC’s International (Regional) Cooperation and Exchange Programs, jointly funded with partner agencies in other countries.
Where can I find current NSFC funding amounts and deadlines?
On NSFC’s official English-language site, nsfc.gov.cn/english, including its annual “Guide to Programs” publication and International Cooperation section. Because figures and eligibility windows change annually, treat any figure quoted elsewhere (including on this page) as potentially out of date, and confirm current-cycle details directly with NSFC or a prospective Chinese host institution.
