Assessing the Impact of China’s MIRVs on South Asia (Stimson)

Rabia Akhtar, a member of the CTBTO Youth Group, has published an article commenting China’s modernization of its nuclear arsenal, mentioning that “achieving universal ratification and entry into force (EIF) of the CTBT is perhaps the single most important step through which technological determinism prevalent in the strategic competition in Asia can be checked and moderated. However, to generate the momentum for the closure and EIF of the CTBT, the United States and China would need to jointly lead the way by simultaneously ratifying the treaty and then inviting India and Pakistan to simultaneously sign and ratify the CTBT.”

This article was published as a commentary of the book The Lure and Pitfalls of MIRVs: From the First to the Second Nuclear Age, written by Michael Krepon, Shane Mason and Travis Wheeler, and released by the Stimson Center in May 2016.

Entrevistas: Lassina Zerbo (Once Noticias)

In an interview with Mexico’s TV station Canal Once, Executive Secretary Lassina Zerbo speaks about the Treaty of Tlatelolco, which established a nuclear-weapons free zone in Latin America and the Caribbean in 1967, and Mexico’s leadership role in nuclear disarmament and non-proliferation.

“Tlatelolco basically summarizes what Mexico represents for the International Community in terms of arms control, non-proliferation and nuclear disarmamanent’’, Lassina Zerbo says, ‘’Mexico has remain a strong advocate, I mean if you say not only on the issue of CTBT, if you look at the discussion on the NPT at the reviez conference in New-York […] Mexico remains active.”

He also discusses the nuclear non-proliferation challenge posed by North Korea, the only country to continue nuclear testing in this century.



The Executive Secretary of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), Lassina Zerbo, is visiting Israel from 19 to 22 June 2016. He is meeting with Israel’s Prime Minister Benjamin Netanyahu and other political leaders and high-level representatives including Yuval Steinitz, Minister of Energy and Water Resources, Zeev Snir, the head of the Israel Atomic Energy Commission (IAEC), the body responsible for cooperation with the CTBTO and with Jacob Nagel, acting head of the National Security Council. It is the first time a CTBTO Executive Secretary meets the Prime Minister of Israel.

Later today, Zerbo will address an official dinner to mark the 20th anniversary of the Comprehensive Nuclear-Test-Ban Treaty, jointly hosted by the heads of the IAEC and the Institute for National Security Studies (INSS).


The CTBT bans all nuclear explosions, thus hampering both the initial development of nuclear weapons as well as significant enhancements (h-bomb). The Treaty also helps prevent damage caused by nuclear testing to humans and the environment.

The CTBT has so far been signed by 183 States and ratified by 164. Its entry-into-force formula prescribes that 44 particular “nuclear technology holder” States need to ratify for it to enter into force. Eight of them have yet to ratify: In the Middle East, Egypt, Iran and Israel; outside the region, China, the Democratic People’s Republic of Korea (DPRK), India, Pakistan and the United States (the DPRK, India and Pakistan have also not yet signed the Treaty).

A verification regime to monitor the globe for nuclear explosions is nearing completion with around 90 percent of the 337 planned International Monitoring System (IMS) facilities already in operation. The three IMS facilities in Israel are certified and sending data to the CTBTO in Vienna.
