On the one hand, it will take time to negotiate and not all States may ratify it.

Recommendations for Measures to be Taken in the Short-Term Therefore, while further consideration is given to the most appropriate and best way to approach the possible drafting and implementation of a new convention on related issues in the long-term, immediate measures need to be taken in order to respect the best interests of children concerned.
