The Nationwide Ceasefire Agreement (NCA; Burmese: တစ်နိုင်ငံလုံး ပစ်ခတ်တိုက်ခိုက်မှု ရပ်စဲရေးသဘောတူစာချုပ်) was a landmark ceasefire agreement between the government of Myanmar and representatives of various ethnic insurgent groups, officially known as "ethnic armed organisations" (EAOs) by the government. The draft was agreed upon by a majority of the invited parties on 31 March 2015, and the agreement was signed by President Thein Sein on 15 October 2015. The signing was witnessed by observers and delegates from the United Nations, the United Kingdom, Norway, Japan and the United States. A ceremony is held by the government annually on the anniversary of the signing of the agreement.
