Universal ratification of the Optional Protocol on the Involvement of Children in Armed Conflict will establish an international moral consensus that no child should take part in hostilities or be involuntarily recruited and that former child soldiers should be assisted by their governments after a life of violence and distress.

The future of any leader or political systems is to be determined by the people of the country.

Three decades into this crisis, let us set our sights on achieving the "three zeros" zero new HIV infections, zero discrimination and zero AIDS-related deaths.

The power of the leader is given to him by the people, so he has a duty to engage and listen more attentively and carefully to the aspirations of the people.

Saving our planet, lifting people out of poverty, advancing economic growth... these are one and the same fight. We must connect the dots between climate change, water scarcity, energy shortages, global health, food security and women's empowerment. Solutions to one problem must be solutions for all.

Now it is the least developed world who are not responsible for this climate change phenomenon that bore the brunt of climate change consequences so it is morally and politically correct that the developed world who made this climate change be responsible by providing financial support and technological support to these people.

Climate change does not respect border; it does not respect who you are - rich and poor, small and big. Therefore, this is what we call global challenges, which require global solidarity.
