This is going to be his first visit to Bangladesh since assuming the post on August 1, 2013, said an official on Monday.
In November 2016, the Member States of the highest decision-making body of the CTBTO preparatory commission re-appointed Executive Secretary Zerbo to a further four year term of office until July 31, 2021.
He will hold a bilateral meeting with Secretary, Ministry of Science and Technology Md Anwar Hossain as his visit will begin through visiting Bangabandu Memorial Museum on Thursday.
He will also hold a meeting with Foreign Minister AH Mahmood Ali and will deliver a lecture at Bangladesh Institute of International and Strategic Studies (BIISS) on the importance of nuclear test ban.
The Comprehensive Nuclear Test Ban Treaty (CTBT) bans nuclear explosions by everyone, everywhere: on the Earth's surface, in the atmosphere, underwater and underground.
