QUNO co-organised platforms for civil society leaders and practitioners to present their work and interact with professionals from governments and development cooperation agencies on Armed Violence and Development, during regional "Best Practice" seminars in Nairobi, Rio de Janeiro, Kathmandu, Abuja and Zagreb. These seminars were held between between November 2010 and September 2011.

In June 2011, QUNO New York worked with other partner organisations to publish a public statement in response to fighting that had erupted in northern Myanmar. The statement included recommendations for immediate action by the Government of Myanmar and the Kachin Independence Army, as well as supportive measures to be taken by China, the Association of Southeast Asian Nations (ASEAN), and the UN.
