尽管人们对联合国的效力存在合理的疑问，但在应对世界多重挑战方面，联合国依然是多边主义和国际合作的典型代表。它仍然是一个理想的框架，在这个框架内，世界上所有国家，无论强弱、享有和平或陷于危机，也不论是发达国家或是发展中国家，都有机会自由表达自己的意见，平等参与关于当今重大国际问题的辩论、谈判和决定。
Despite legitimate questions about its effectiveness, the United Nations continues to quintessentially embody multilateralism and international cooperation in responding to our world’s multiple challenges. It remains the ideal framework within which all the nations of the world — be they powerful or less powerful; at peace or in crisis; or developed or developing — have the opportunity to express themselves freely and participate equally in debates, negotiations and decisions on the major international issues of the day.
