I am not a national leader. If I am a national leader I can speak out all that I want.

Climate change...is, simply, the greatest collective challenge we face as a human family.

One of my earliest memories is walking up a muddy road into the mountains. It was raining. Behind me, my village was burning. When there was school, it was under a tree. Then the United Nations came. They fed me, my family, my community.

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.

Climate change is destroying our path to sustainability. Ours is a world of looming challenges and increasingly limited resources. Sustainable development offers the best chance to adjust our course.

I strongly reject threats by any member state to destroy another or outrageous attempts to deny historical facts such as the Holocaust.

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.
