Here are portions of President Carter's toast delivered during a working dinner with Soviet President Leonid Brezhnev at the U.S. Ambassador's residence last night :

We have come to Vienna in search of common understanding in a spirit of common sense. We have come to explore, to clarify and to attempt to resolve our differences. We have come to take one more step toward avoiding a nuclear conflict which some few might survive but which no side could win.

Mr. President, if I had only one thing to mention in my toast tonight, it would be to propose our two nations' success in holding a steady course toward control of weapons, and in halting any drift towards uncertainty that might come from our failure to control and regulate the arms competition . . ..

In fact our new SALT treaty could provide the basic framework we seek to reduce tension and conflict throughout the world. That world is moving quickly toward more varied forms of government. Young nations are asserting a new independent place for themselves. We are seeing the decline of racism, and the end of colonialism. There is a worldwide movement against poverty and social injustice.

At the same time, we face dangers that create combat in some regions, trouble international relations on a global scale, and encourage the spread of nuclear and conventional arms.

We see our own role as one that supports change toward greater pluralism in and among societies. We want more equality and economic opportunities for developing nations.

We believe in restraining conflicts that could undermine those goals.

We are working for cooperation among nations, for the peaceful settlement of disputes, for economic development, social justice and human rights around the globe.

These are the ideas we would like to explore as we discuss the unique responsibilities of the relationship between the United States and the Soviet Union.

That we have the power to destroy other nations does not mean we have a right or a need to control them.

I believe that our successful effort to limit nuclear weapons can be a framework for guidance toward new areas of cooperation, and for facing peacefully those areas in which we still compete.
