I look forward to strengthening the U.S.-U.N. partnership and working closely with Secretary of State Kerry towards our shared goals of peace, development, and human rights.

I have been very encouraged by President Obama's call to action on climate change both at his Inauguration and in the State of the Union Address. This is a global imperative. I also welcome President Obama's intention to pursue reductions in nuclear arsenals.

It is important that the right of Israel to exist should be respected and also the viable Palestinian authorities, in terms of political and financial situation, be supported so that both can live side by side in peace and security. That is a two-state solution.

We have international standards regulating everything from t-shirts to toys to tomatoes. There are international regulations for furniture. That means there are common standards for the global trade in armchairs but not the global trade in arms.

Weapons of mass destruction violate more than individual lives - they cross international borders and jeopardize all people. They also drain resources that could be used instead for medicines, schools and other life-saving supplies. We must come together with even greater determination to prevent a WMD nightmare.

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.

Whether addressing immediate crises or building long-term foundations of peace, the United Nations will remain committed to solutions that advance the global good.

I have been, and will remain, outspoken in my insistence that Israel has a right to live in peace and security.

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 disarmament is one of the greatest legacies we can pass on to future generations.

We must eliminate all nuclear weapons in order to eliminate the grave risk they pose to our world. This will require persistent efforts by all countries and peoples. A nuclear war would affect everyone, and all have a stake in preventing this nightmare.

The U.N.'s humanitarian agencies rely on charitable donations from the public as well as the generosity of governments to continue their lifesaving work in response to natural disasters, armed conflicts and other emergencies.

At a time when we aim to accelerate our efforts to achieve the Millennium Development Goals and define a bold agenda for the period beyond 2015, the role of charity can and should grow. U.N. bodies such as the U.N. Volunteers Programme and UNICEF offer venues for people across the world to get involved.

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.

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

I believe that the topic of chemical weapons is critically important for international peace and security, and I take note of the ongoing debate over what course of action should be taken by the international community. All those actions should be taken within the framework of the U.N. Charter, as a matter of principle.

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.

Sustainable development is the pathway to the future we want for all. It offers a framework to generate economic growth, achieve social justice, exercise environmental stewardship and strengthen governance.

I was profoundly moved to be the first United Nations Secretary-General to attend the Peace Memorial Ceremony in Hiroshima. I also visited Nagasaki. Sadly, we know the terrible humanitarian consequences from the use of even one weapon. As long as such weapons exist, so, too, will the risks of use and proliferation.

Some might complain that nuclear disarmament is little more than a dream. But that ignores the very tangible benefits disarmament would bring for all humankind. Its success would strengthen international peace and security. It would free up vast and much-needed resources for social and economic development. It would advance the rule of law.

Pacific Islands are among those that contribute least to global warming, yet suffer most.

We must confront persecution faced by many Christian communities and the intolerance that plagues us. We must overcome anti-Semitism and the prejudice that divides us. We must defeat Islamophobia and the fears that weaken us.

Building sustainable cities - and a sustainable future - will need open dialogue among all branches of national, regional and local government. And it will need the engagement of all stakeholders - including the private sector and civil society, and especially the poor and marginalized.

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.
