Looking at the list, I see that most countries have merely signed the convention at one of the formal ceremonies that have been held, as in October or November 2017, or January 2018. However, those countries have done nothing more since signing. What do you expect of all those that thus far have merely signed the convention without taking any further measures? Do you expect that a majority of those countries will ratify the convention and bring it into force or that nothing will change in the next few years?
