The Committee on the Rights of the Child noted that "when States ratify the Convention, they take upon themselves obligations not only to implement it within their jurisdiction, but also to contribute, through international cooperation, to global implementation." 84 The next subsections explore the emerging extraterritorial obligations to respect, protect and fulfill the reasonable minimum core of economic and social rights. States' obligations to respect the reasonable minimum core of economic and social rights is a negative right and thereby obliges states to refrain from interfering in the enjoyment of individuals' economic and social rights both within and outside its territorial borders. 85 The extraterritorial obligation to respect suggests that states must undertake due diligence ensuring not only that they comply with human rights obligations concerning the reasonable minimum core economic and social rights, but that they additionally do everything possible to avoid causing harm to them. The United Nations Millennium Declaration recognizes that "we have a collective responsibility to uphold the principles of human dignity, equality and equity at the global level. As leaders we therefore have . . . a duty to all the world's people, especially 86 the most vulnerable and, in particular, the children of the world., Several international treaties and documents support extraterritorial obligations of states to respect economic and social rights. 87 For instance, the Convention on the Rights of Persons with Disabilities affirms, "the importance of international cooperation for improving the living conditions of persons with disabilities in every country, particularly in developing countries., 88 Cooperatively, state parties commit that they, "will undertake appropriate and effective measures in this regard, between and among States and, as appropriate, in partnership with relevant international and regional organizations and civil society, in particular organizations of persons with disabilities." 89 The measures that states can adopt to ensure respect for the reasonable minimum core of economic and social rights include: acknowledging them in external policies, constantly and consistently examining human rights situations where economic and social rights are at stake, effectively monitoring policies that protect economic and social rights, and implementing an 84 Comm. on the Rights of the Child, General Comment No. 5, General measures of implementation of the Convention on the Rights of the Child, U.N.
