Another example that shows the importance of non-state actors in peace-building is the contribution of ICBL (International Campaign to Ban Landmines) to the international prohibition on the use of landmines. ICBL is a global network of NGOs that has operated in over 90 countries since 1992. Its primary goal is to make a world free of anti-personnel landmines. Their passionate advertising appealing for global cooperation drew Diana, Princess of Wales to become an ardent advocate. Together, they brought the issue to the United Nations General Assembly. ICBL's efforts led the international community to urge states to ratify the Ottawa Treaty (Mine Ban Treaty) in 1997, and its contribution was recognized and praised as it was awarded the Nobel Peace Prize in the same year.
