I believe in a world of justice and human rights for all. A world where girls can grow up free of fear of abuse. A world where women are treated with the respect and dignity that is their right. A world where poverty is not acceptable. My dear young friends, you can make this your world.

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.

You are already leaders. Your ideas, your actions and your decisions make a difference. More than any other generation, you have a voice. Social networking is changing how we interact - and it can change our world. You are in touch with peers from around the world. You understand the power of instant communication. I appeal to you to use that power for the common good, the power of communication and the power of networking.

Every literate woman is a victory over poverty

Men must teach each other that real men do not violate or oppress women - and that a woman's place is not just in the home or the field, but in schools and offices and boardrooms.

To measure the success of our societies, we should examine how well those with different abilities, including persons with autism, are integrated as full and valued members.

You have to work and think about how we can make this world a better place for all. This is what I'd really like to ask our young leaders. We will try as leaders of today to minimise the problems which we will hand over to you. But it is to you. You have to take ownership and leadership of tomorrow. For that to be possible, you have to strengthen your capacity and widen your vision as a global citizen.
