The host country (Chair-in-Office) assumes responsibility for the preparatory process and the implementation of each Forum. The host government chairs all sessions related to Forum preparations and chairs the Forum. The Chair-in-Office is assisted by the country that organized the previous Forum and the country that will host the following meeting of the Forum, through the Troika.
The Chair-in-Office should, in principle, alternate between developing and developed countries. Countries interested in assuming the Chair of the Forum shall communicate their intention to the Troika.
