Belfer Center experts offer insight and analysis of the Trump-Kim summit through statements and interviews.

In this oped for the Bulletin of the Atomic Scientists, Hui Zhang contributes a third article to an international roundtable on reprocessing:

"Since 1983, a closed fuel cycle has been an official element of China's nuclear energy policy. According to proponents, plutonium reprocessing and breeder reactors will allow full utilization of China’s uranium resources, drastically reduce the volume of radioactive waste that must be stored in an underground repository, and establish a way to dispense with the spent fuel accumulating in China’s reactor pools. But Beijing's attempts to develop commercially viable reprocessing facilities and breeder reactors have been afflicted with technological difficulties, serious delays, and cost overruns. At this point—especially taking into account China's ample uranium resources and its easy access to additional resources abroad—it appears very doubtful that reprocessing and fast reactors are the proper way forward for China's nuclear energy sector..."

"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."

Hui Zhang presented "Strengthening China-U.S. Cooperation on Nuclear Security" at the U.S.-China Nonproliferation and Nuclear Security Dialogue in Washington, D.C., June 26–27, 2014.

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".

"President Barack Obama and Kim Jong-eun could end up confronting each other 'eyeball to eyeball', each with nuclear weapons on hair trigger, as president John F Kennedy and Nikita Khruschev did over five decades ago during the Cuban missile crisis in 1962. However, the younger and less-experienced Kim of the smaller and isolated Kingdom might not behave as rationally as Khruschev."

"From China's perspective, the crisis is driven by Washington and Pyongyang. North Korea is unlikely to give up its nuclear ambitions until it gets from the U.S. what it covets most: a reliable security assurance. This would mean an end to Washington's pursuit of regime change. If Washington does not move in this direction, Pyongyang will continue to escalate the crisis. Any resolution of the impasse has to address the reasonable security concerns of North Korea."

Hui Zhang argues that China's pledge of no-first-use of nuclear weapons, while constraining its nuclear force at a minimum level, maintaining its deeply de-alerted status, and upholding its long-standing position to support complete nuclear disarmament, has set a good example for other nuclear nations, in particular the two nuclear superpowers.  Zhang suggests that Beijing believes that all nuclear states should adopt a no-first-use policy and redefine the role of nuclear weapons in their national security doctrines. Although China stands ready to support the nuclear-free agenda, it is up to the two countries with the overwhelming number of the world's warheads to take the lead.
