Like the United Nations, there is something inspirational about New York as a great melting pot of different cultures and traditions. And if this is the city that never sleeps, the United Nations works tirelessly, around the clock around the world.

A world free of nuclear weapons will be safer and more prosperous.

Chemical weapons simply have no place in the 21st century. Progress in this vital area will help generate momentum to meet our goal of eliminating all weapons of mass destruction.

Any use of chemical weapons, by anyone, under any circumstances, is a grave violation of the 1925 Protocol and other relevant rules of customary international law.

Countries with higher levels of gender equality have higher economic growth. Companies with more women on their boards have higher returns. Peace agreements that include women are more successful. Parliaments with more women take up a wider range of issues - including health, education, anti-discrimination, and child support.

Charity plays an important role in upholding the values and advancing the work of the United Nations.

We have reached a new milestone as a human family. With seven billion of us now inhabiting our planet, it is time to ask some fundamental questions. How can we provide a dignified life for ourselves and future generations while preserving and protecting the global commons - the atmosphere, the oceans and the ecosystems that support us?

The burden for achieving disarmament cannot be borne by peace groups alone. Everybody, regardless of age, income, profession, gender or nationality, has a stake in this quest.

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.

By including children with different learning abilities in mainstream and specialized schools, we can change attitudes and promote respect. By creating suitable jobs for adults with autism, we integrate them into society.

New York is one of the greatest cities in the world. It is a fitting host to its many international visitors, who can come to witness first-hand what a vibrant multicultural democracy looks like.

The possibility that terrorist groups could obtain weapons of mass destruction should not be dismissed as a fiction. This is a horrific threat the international community should take seriously. As long as these weapons exist, so, too, does the risk of their use - by accident or design.

Every day, we at the United Nations see the human toll of an absence of regulations or lax controls on the arms trade. We see it in the suffering of civilian populations trapped by armed conflict or pervasive crime. We see it in the killing and wounding of civilians - including children, the most vulnerable of all.

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.

The United Nations has a proud record of helping millions of people in mine-affected countries.

Women can drive progress towards the central goals of mine action, which aims to increase security, rebuild communities, reclaim land and end the looming fear caused by explosive remnants of war.

Nuclear tests poison the environment - and they also poison the political climate. They breed mistrust, isolation and fear.

Women and girls are disproportionately affected by landmines. They have different needs when it comes to education about risks. And they may face greater challenges when a family member is killed or injured.
