Nuclear disarmament and non-proliferation are not utopian ideals. They are critical to global peace and security.
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.
My U.N. five-point plan focuses on preventing proliferation, strengthening the legal regime, and ensuring nuclear safety and security - an effort that was given good momentum by the Nuclear Security Summit held in Seoul earlier this year. The world is over-armed, and peace is underfunded.
The catastrophic humanitarian consequences of any use of nuclear weapons require that it be treated as a top priority. Disarmament will work better than any alternative in reducing the risk of use.
Cities can be the engine of social equity and economic opportunity. They can help us reduce our carbon footprint and protect the global environment. That is why it is so important that we work together to build the capacity of mayors and all those concerned in planning and running sustainable cities.
I take very seriously my responsibility as Secretary-General to make sure that the United Nations is doing everything it can to uphold the universal prohibition on the use of chemical weapons.
Our planet's lands and oceans are already stretched to meet the demands of 7 billion people. The human population continues to grow. The search for sustainable solutions is an economic and a moral imperative if we are to create the future we want.
Charity plays an important role in upholding the values and advancing the work of the United Nations.
Europe and Africa share proximity and history, ideas and ideals, trade and technology. You are tied together by the ebb and flow of people. Migration presents policy challenges - but also represents an opportunity to enhance human development, promote decent work, and strengthen collaboration.
One of the main lessons I have learned the last five years as Secretary-General is that the United Nations cannot function properly without the support of the business community and civil society. We need to have tripartite support - the governments, the business communities and the civil society.
Grave security concerns can arise as a result of demographic trends, chronic poverty, economic inequality, environmental degradation, pandemic diseases, organized crime, repressive governance and other developments no state can control alone. Arms can't address such concerns.
Strangely, charity sometimes gets dismissed, as if it is ineffective, inappropriate or even somehow demeaning to the recipient. 'This isn't charity,' some donors take pains to claim, 'This is an investment.' Let us recognize charity for what it is at heart: a noble enterprise aimed at bettering the human condition.
We have a legal and moral obligation to rid our world of nuclear tests and nuclear weapons.
All women and girls have the fundamental right to live free of violence. This right is enshrined in international human rights and humanitarian law. And it lies at the heart of my UNiTE to End Violence against Women campaign.
Climate change, in some regions, has aggravated conflict over scarce land, and could well trigger large-scale migration in the decades ahead. And rising sea levels put at risk the very survival of all small island states. These and other implications for peace and security have implications for the United Nations itself.
The human family is at a critical juncture. The world is moving through a great transition. This transition is economic, as the digital revolution advances and as new powers and groups emerge.
Not many countries establish a prize for peace. The Seoul Peace Prize has its roots in the 1988 Summer Olympics when this country opened its doors to people and athletes from more than 160 countries. Korea did so in part because it believes in the power of sports for peace and development.
All nuclear material in weapons programmes must be subject one day to binding international verification.
Women hold up more than half the sky and represent much of the world's unrealized potential. They are the educators. They raise the children. They hold families together and increasingly drive economies. They are natural leaders. We need their full engagement... in government, business and civil society.
Frankly speaking, I don't know much about rock music. But I enjoyed some when I was in college or high school. But I stopped listening after Elvis Presley!
Since I became Secretary-General, five years ago, I have seen youth participate at the United Nations as never before.
True security is based on people's welfare - on a thriving economy, on strong public health and education programmes, and on fundamental respect for our common humanity. Development, peace, disarmament, reconciliation and justice are not separate from security; they help to underpin it.
Nuclear tests poison the environment - and they also poison the political climate. They breed mistrust, isolation and fear.
