Chinese President Xi Jinping addresses China’s new concept of nuclear security with four “equal emphasis” at the third Nuclear Security Summit, and makes four commitments to strengthen nuclear security in the future. To convert President Xi’s political commitments into practical, sustainable reality, China should take further steps to install a complete, reliable, and effective security system to ensure that all its nuclear materials and nuclear facilities are effectively protected against the full spectrum of plausible terrorist and criminal threats. This paper suggests the following measures be taken to improve China’s existing nuclear security system, including updating and clarifying the requirements for a national level DBT; updating and enforcing existing regulations; further promoting nuclear security culture; balancing the costs of nuclear security, and further strengthening international cooperation on nuclear security.

"Since the 9/11 attacks, China has made significant progress on its nuclear security system, with a focus on switching from the traditional “guns, gates, guards” approach to an effective mixed approach that combines well-trained personnel with up-to-date techniques and technology. The major advancements include a security approach based on a design basis threat (DBT); application of modern concepts of physical protection, based on systems-engineering approaches to analyzing vulnerabilities and designing defenses to address them; the use of modern physical protection, material control, and material accounting technologies; requirements for in-depth vulnerability assessments of security systems; and improvements to the organization of nuclear security and guard force training and equipment on the part of facility operators..."

China is in beginning stages of significantly expanding its reprocessing program. As it considers the costs and benefits of its plan, Beijing should include the inherent security risks that come with extracting weapons-useable plutonium from spent nuclear fuel.

In this presentation for the Institute for Nuclear Materials Management 55th Annual Meeting in Atlanta, Georgia, July 20-24, 2014, Hui Zhang discusses the issue of reducing the danger of nuclear terrorism in China.

"The Chinese government has taken significant steps to develop and apply approaches to nuclear security and nuclear accounting in the aftermath of 9/11. One driver of Chinese improvements has been international cooperation, in particular with the US. Since the 9/11 attacks, China has actively cooperated with the US to improve its nuclear security in the civilian sector. Such cooperation should continue and grow stronger. More importantly, China-US cooperation should extend to the military sector that has custody of the largest stocks of weapon-usable fissile materials and all nuclear weapons."

Recent news reports say that Japan failed to disclose the existence of about 640 kilograms of unused plutonium—enough to make about 80 nuclear bombs—in its annual reports to the International Atomic Energy Agency (IAEA) in 2012 and 2013. This has raised Chinese concerns about Japan’s plutonium program...

Japanese officials claim that this under-reporting was an honest error of interpretation of the rules, because the material in question was part of the plutonium-uranium mixed oxide (MOX) fuel stored in a reactor that happened to be offline during this period.

Many Chinese worry that as Japanese politics moves rightward, it could result in the country seeking its own weapons. Beijing's concerns have intensified with its confrontation with the Abe administration over historical recognition and territorial issues. In this op-ed, Hui Zhang argues that it is time for Tokyo to stop reprocessing and eliminate its surplus plutonium as soon as possible. Tokyo should address concerns over its reprocessing plans and plutonium stocks. To reduce suspicions, Tokyo should take specific steps to abide strictly by its "no surplus plutonium policy".

The most significant achievement to emerge from the 2014 Nuclear Security Summit was a pledge by 35 countries to observe the terms of a joint agreement, known as Strengthening Nuclear Security Implementation. Promoted strongly by the chairs of all three nuclear summits—the United States, South Korea, and the Netherlands— the 2014 initiative is an important step towards creating a robust global security system designed to prevent nuclear materials from falling into the hands of terrorists. Yet China, along with Russia, India, and Pakistan, did not join the pledge. Beijing has not offered any explanations. China not only can join the new initiative, it should join it—because joining is in China’s own national interest.
