About the event

Proliferation of conventional weapons and weapons of mass destruction, as well as high-priority and dual-use items have been in the spotlight for quite some time. With the growing and shifting geopolitical tensions of the last decade, these topics have also gained deeper strategic importance and have been perceived by many states as foreign policy priority. Influencing the existing conventions, fora, and policies to suit their own interests has become a longstanding goal of many powerful international actors, while the possible erosion of the multilateral disarmament and non-proliferation architecture has worried diplomats and experts alike.

In his lecture, Ondrej Hajn will present the differences between Disarmament, Non-Proliferation, and International Control Regimes, and shed some light on how these fields interact with each other. He will elaborate on the associated challenges, and offer the Czech perspective, including the latest experiences and views. The lecture will pose a critical question of why it is vital to sustain the international control regimes, disarmament, and non-proliferation architecture.
