A/HRC/27/49 disappearance, to assist States in reducing obstacles to implement the Declaration, and to ensure direct contact with the family members of victims. There are, however, a number of States from which the Working Group has requested invitations to visit, which have not been forthcoming. Those States include Bangladesh, Belarus, Burundi, China, Egypt, India, Indonesia, Kenya, Nepal, Nicaragua, the Philippines, the Russian Federation, South Sudan, Sri Lanka, the Sudan, the Syrian Arab Republic, Thailand, Turkey, the United Arab Emirates, Uzbekistan, and Zimbabwe. There are others that have informally invited the Working Group to visit and/or confirmed invitations, but for which specific dates to visit have not been agreed, such as Algeria and the Islamic Republic of Iran. The Working Group therefore calls upon all States with pending requests for visits to respond favourably to them in the light of Human Rights Council resolution 21/4, and those that have agreed to visits to respond as soon as possible with specific dates. 121. The Working Group once again calls upon States that have not signed and/or ratified the International Convention for the Protection of All Persons from Enforced Disappearance to do so as soon as possible and to accept the competence of the Committee on Enforced Disappearances to receive individual cases under article 31, and inter-State complaints under article 32 of the Convention. 122. The Working Group carries out a wide range of activities and receives an increasing number of demands from various stakeholders. The resources that have been provided to the Working Group under the regular budget are unfortunately not sufficient for it to respond to all requests. That also prevents the Working Group from properly planning its activities. The Working Group continues to periodically receive newly reported cases of enforced disappearance from across the globe while dealing with a backlog standing at around 600 cases. The Working Group is grateful to the Governments of Argentina and France for their financial contributions, which allowed the Working Group to have enhanced support, but emphasizes the need to provide additional support to the mandate under the regular budget of the United Nations. At the same time, it calls on all States for greater assistance to allow it to accomplish its mandate. 123. The Working Group concludes by emphasizing how the changing situation of enforced disappearance requires new strategies to counter that crime and urges States to strengthen measures to prevent and eradicate enforced disappearance and to secure the rights to truth, justice and reparations of victims. 25
