 At the national level, the Swiss Campaign to Ban Landmines successfully advocated in favor of a national ban of antipersonnel landmines and of Switzerland’s signature and ratification of the Ottawa Treaty in 1995-1997.Within the ICBL, the Swiss Campaign was a member of the "Non State Actors Working Group", which it co-chaired until the end of 2004.The Swiss Campaign has also participated in the creation of Geneva Call, which primarily aims at engaging armed non-state actors in a total ban of antipersonnel landmines.
