In the early 1990s, Küng initiated a project called "Weltethos" ("Global Ethic"), which is an attempt at describing what the world's religions have in common (rather than what separates them) and at drawing up a minimal code of rules of behaviour that everyone can accept. His vision of a global ethic was embodied in the document "". This Declaration was signed at the 1993 Parliament of the World's Religions by religious and spiritual leaders from around the world. Later Küng's project would culminate in the United Nations Year of Dialogue Among Civilizations (2001) to which Küng was assigned as one of 19 "eminent persons". Even though it was completed shortly after the terrorist attacks of 9/11 (in September 2001), it was not covered in the U.S. media, a fact about which Küng complained.
