"Observations on Lack of Transparency in China’s Nuclear Arms Expansion"

SPF China Observer

Organized by: Sasakawa Peace Foundation
The Sasakawa Peace Foundation (SPF) has been conducting a project to publish research papers to analyze China's politics, economy, society, diplomacy, and security by Japanese experts through a satellite website, SPF China Observer. In addition, public forums are periodically held with the authors of this project.

In this second session of FY 2022, we will discuss China’s lack of transparency in its nuclear arms expansion, which is occurring against the backdrop of increasing focus on the significance of nuclear weapons following Russia's invasion of Ukraine and nuclear threats against Western countries. These developments have underscored the need to demonstrate the effectiveness of nuclear disarmament within the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) framework. The speaker will be Yuki Kobayashi, SPF research fellow and author of “Observations on Lack of Transparency in China’s Nuclear Arms Expansion: Ahead of the NPT Review Conference.” The discussant will be Professor Akio Takahara of the University of Tokyo, who is also the editor of the SPF China Observer. Additionally, SPF Senior Fellow Bonji Ohara will moderate the discussion.

We look forward to your participation.
