China Daily's publisher Zhou Shuchun delivers a speech at Vision China

The changes in the world over the past 75 years have demonstrated that the United Nations plays an irreplaceable role in responding to major global challenges, Zhou Shuchun, publisher and editor-in-chief of China Daily, said at the Vision China event on Wednesday.

The UN is the most universal, authoritative and internationally representative intergovernmental organization and its charter is the cornerstone for the fundamental principles of contemporary international relations and order, Zhou said.
