The United States continues to call upon Sudan and South Sudan to exercise maximum restraint and to reach a negotiated settlement to the outstanding issues between them.

I want to say how much I appreciate the opportunity to meet once again with Prime Minister Gilani and his delegation.

Both parties recognize that the Exchange of Notes between the US and Japan on 9 March 2012 setting out the terms and conditions of their cooperation in the fields of nuclear security and other areas will facilitate those projects.

It is wonderful to see you again and your delegation.

I'm looking forward, as always, to a constructive and frank and productive meeting that can ultimately benefit both the peoples of China and the peoples of the United States.

There is time and space for diplomacy, but people also have to understand that that time is not unlimited.

I think that the fact that we have met 11 times during the course of my Presidency is an indication of the importance that both of us place on strong U.S.-China relations.

I look forward to continuing to strengthen the relationship between our two countries.

We both have an interest in making sure that international norms surrounding nonproliferation and preventing destabilizing nuclear weapons is very important.

Moving forward, we've got more work to do between our two countries.

The last 3 years of my work with President Medvedev has been extremely productive.

I emphasized to the Prime Minister once again that I believe there is a window of time to resolve this question diplomatically, but that window is closing.

North Korea knows its obligations, and it must take irreversible steps to meet those obligations.

Let me say again that if the Iranian Government pursues a responsible path, it will be welcome once more among the community of nations.

I have said before, Ireland punches above its weight internationally and has a long history rooted in its own experience of making sure that not only is peace a priority.

There is no reason for the United States and Iran to be divided from one another.

I look forward to a productive visit to Cartagena.

We prefer dialogue.
