UN General Assembly
1967

38. It has taken the United Nations twenty-one years to bring to this podium, as its President, a representative of one of the socialist group of countries. This is significant and symbolic. The United Nations has come of age and has demonstrated that degree of political maturity necessary to appreciate the process of political and economic evolution that has resulted in two principal political and economic ideologies establishing themselves in the world, each with its right to exist and to compete for recognition and acceptance without resort to violence and compulsion. Each of the systems has its own efficacy and value, and the lesson that twenty-one years of the United Nations existence has taught us is that the two political and economic systems must exist in a spirit of mutual tolerance if peace and harmony are to prevail in the world.
