At the invitation of Mr. Vesselin Popovski, Director of Peace and Governance Programme of the United Nations University, Professor Hasegawa spoke to a group of about 20 graduate students for two hours on 20 October 2011. The students were from Africa, Asia, Australia, Europe and New Zealand. Half of them were studying for masters degrees, while the rest pursued a six week international course.
　Upon completion of Professor Hasegawa’s discourse, the students asked many questions and engaged in a lively discussion on how the doctrines, policies and practices of UN peacekeeping operations changed over the past two decades since the end of the Cold War.
