We have agreed that it is necessary to sustain the responsible effort which the Government of Bolivia is now making--through the COMIBOL--to restore more efficient production of Bolivia's principal export, tin.

We are particularly glad to welcome the President of Bolivia because this has been his life work--in years of exile as well as years of the Presidency he has attempted to maintain a free country, national sovereignty, unimpaired, and at the same time provide--with the geography not always his friend--provide a better life for his people.

I think the United States values its relations with the countries of Latin America because of historical reasons, cultural reasons, hemispheric ties, geography, and all the rest, probably more warmly than it does any of its obligations and responsibilities around the world.

This is a difficult challenge in this hemisphere.

I know that I speak on behalf of all of our countrymen in welcoming our guest of honor.

I am proud to be a member of it.

And, building on that rich base, I see no reason why we cannot fulfill our obligations abroad.

I do not look to the future with gloom.

The means of achieving it are difficult, but our objective is simple, and that is to provide for our people a rising rate of well-being.
