A/RES/60/129 that measures to provide complementary forms of protection should be implemented in a manner that strengthens the existing international refugee protection regime; 15. Notes that local integration in the refugee context is a sovereign decision and an option to be exercised by States guided by their treaty obligations and human rights principles and that it is a dynamic and multifaceted two-way process that requires efforts by all parties concerned, including a preparedness on the part of refugees to adapt to the host society without having to forego their own cultural identity and a corresponding readiness on the part of host communities and public institutions to welcome refugees and to meet the needs of a diverse population, and acknowledges that the process of local integration is complex and gradual, comprising three distinct but interrelated legal, economic, and social and cultural dimensions, all of which are important to the ability of refugees to integrate successfully; 16. Acknowledges that the global refugee situation represents an international challenge requiring that international burden- and responsibility-sharing be addressed effectively, and recognizes that allowing for local integration, where applicable, is an act of States that is a durable solution for refugees, which contributes to the said burden- and responsibility-sharing, without prejudice to the specific situation of certain developing countries facing mass influxes; 17. Emphasizes the obligation of all States to accept the return of their nationals, calls upon States to facilitate the return of their nationals who have been determined not to be in need of international protection, and affirms the need for the return of persons to be undertaken in a safe and humane manner and with full respect for their human rights and dignity, irrespective of the status of the persons concerned; 18. Condemns all acts that pose a threat to the personal security and wellbeing of refugees and asylum-seekers, such as refoulement, unlawful expulsion and physical attacks, and calls upon all States of refuge, in cooperation with international organizations where appropriate, to take all necessary measures to ensure respect for the principles of refugee protection, including the humane treatment of asylum-seekers; 19. Affirms the importance of mainstreaming the protection needs of women and children to ensure their participation in the planning and implementation of programmes of the Office of the High Commissioner and State policies and the importance of according priority to addressing the problem of sexual and gender-based violence; 20. Encourages the Office of the High Commissioner to continue to improve its management systems and to ensure effective and transparent use of its resources, recognizes that adequate and timely resources are essential for the Office to continue to fulfil the mandate conferred upon it through its statute 11 and by subsequent General Assembly resolutions on refugees and other persons of concern, recalls its resolutions 58/153 of 22 December 2003, 58/270 of 23 December 2003 and 59/170 of 20 December 2004 concerning the implementation of paragraph 20 of the statute of the Office, and urges Governments and other donors to respond promptly to annual and supplementary appeals issued by the Office for requirements under its programmes; _______________ 11 4 Resolution 428 (V), annex.
