I spend most of my time in South Korea but at least one-third of my time is spent traveling around the world, meeting people, speaking about climate change and sustainable development and trying to foster global citizenship especially for young people. What I observe is there clearly is a need for global citizenship. That is exactly right. We are having troubles around the world. We need global vision.

Let us acknowledge and celebrate what youth can do to build a safer, more just world. Let us strengthen our efforts to include young people in policies, programmes and decision-making processes that benefit their futures and ours.

Terrorism is a significant threat to peace and security, prosperity and people.

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.

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.

One of the main lessons I have learned during my five years as Secretary-General is that broad partnerships are the key to solving broad challenges. When governments, the United Nations, businesses, philanthropies and civil society work hand-in-hand, we can achieve great things.

It has been said that knowledge is power. We need to strengthen education systems so that young people can benefit from cultural diversity, and not be victimized by those who exploit differences.
