Siddharth Chatterjee, UN Resident Coordinator in China, delivered a speech at the launch of the UN@80 campaign with China and the "One World: Shared Future" visual exhibition on Tuesday. 

He said that for him the United Nations is more than an institution. It is a thread running through his life, first as a lifeline in his early years, later as a calling in his adult life, and one that he has spent 29 years helping to weave for others.
