China has provided political and technical support for the IAEA’s safeguards function. As a nuclear-weapon State, China concluded a voluntary offer safeguards agreement with the IAEA and brought an Additional Protocol into force in 2002. Under this framework, China has cooperated with the IAEA in the application of safeguards to selected peaceful nuclear facilities. China also joined the IAEA Member State Support Programme in 2007 and undertook research and development work on safeguards verification tools and methods, including work related to measurement uncertainty and safeguards concepts. China has further supported safeguards training through the China-IAEA Joint Training Center on Nuclear Safeguards and Security
China has structured its financial support to the IAEA around a combination of assessed contributions, voluntary funding, and extra-budgetary support. China has consistently fulfilled its assessed obligations to the Agency and gradually increased its financial weight as its overall UN contribution share rose. At the same time, it has become as a reliable contributor to the Technical Cooperation Fund (TCF), emphasizing full and timely payment and supporting capacity-building in developing countries.
In addition, China began providing extra-budgetary contributions and in-kind assistance, particularly in nuclear security and safeguards cooperation. For instance, since 2011 China has made continuous contributions to the IAEA Nuclear Security Fund, supporting capacity-building projects in the Asia-Pacific region and reinforcing its role as a contributor to global nuclear governance.
