A/HRC/30/47 with actors in challenging security environments. In response, the Under-Secretary-General mentioned close collaboration with States and referred to a colloquium in June 2015 to share experiences, including on delivery of security. He also clarified that the United Nations employed private security companies and not private military companies. Finally, he pointed out that the United Nations collaborated with international non-governmental organizations in complex and challenging security environments, including in the Syrian Arab Republic and Yemen. IV. Concluding remarks 76. On 1 May 2015, the Chair-Rapporteur thanked the delegations and expressed gratitude to the experts for their excellent contributions. He mentioned the increased use of private military and security companies in various sectors and contexts, both on land and at sea. Specific challenges discussed included: jurisdiction issues linked to “flags of convenience”; weapons storage in the context of “floating armouries” in international waters, including possible circumvention of national laws limiting the import and export of weapons; ensuring that private military and security companies respected applicable national legislation; and challenges relating to international cooperation in legal matters, in particular mutual legal assistance. 77. The Chair-Rapporteur suggested that the open-ended intergovernmental working group consider including the following text as part of its conclusions and recommendations: [Paragraph 1] The intergovernmental working group noted the multifaceted and diverse issues raised throughout its third and fourth sessions. These included: the distinction between the activities of private military companies and private security companies; measures for registering, licensing and contracting private military and security companies; ensuring accountability and provision of assistance and remedies for victims; possibility of an international regulatory framework; specificities of regulating sea-based private security activities; and the use of private security companies by the United Nations. The intergovernmental working group noted the initiatives undertaken by various stakeholders relating to those issues, while highlighting the challenges that remain. [Paragraph 2] Different views were offered as to how to achieve the shared goal of protecting human rights and ensuring accountability for violations and abuses relating to the activities of private military and security companies. Some delegations proposed that the intergovernmental working group begin elaborating a legally binding instrument for the regulation, monitoring and oversight of private military and security companies, and submitted elements of a draft convention for the consideration of the intergovernmental working group. Other delegations proposed the consideration of the range of options to be explored to further develop an international regulatory framework, including international standards setting and development of guidelines, possibly actions plans or model laws, contract templates based on the Montreux Document, good practices and mutual legal assistance programmes. [Paragraph 3] Taking account of Human Rights Council resolution 28/7 of 26 March 2015, the intergovernmental working group will continue its work on the above-mentioned issues and also recommends further consideration of human rights issues relating to, inter alia, (a) the operation of private military and security companies in the maritime context; (b) the use of private military 20
