A/70/213 years, there has been progress towards the development of a set of globally accepted measurements and indicators on child development that could be used to monitor progress as well as for planning purposes in different countries. 63 Progress on this matter should be accelerated. 101. Certain “core obligations” are not subject to progressive realization and must be implemented immediately. 64 Core obligations include: (a) elaboration of a comprehensive national plan for the right to health, including development, in early childhood; (b) non-discriminatory access to health and other relevant services; (c) equitable distribution of health and other facilities for the right to health in early childhood; and (d) access to a minimum “basket” of health-related services and facilities (A/HRC/7/11, para. 52). International cooperation and assistance 102. The right to health gives rise to an obligation of international cooperation and assistance. 65 High-income States have a duty to provide cooperation and assistance for the right to health in low-income countries. There is a particular obligation to assist with respect to core obligations. Low-income countries also have an obligation to seek appropriate cooperation and assistance. 103. As the global health agenda moves from a survival to a survival and development agenda, the Special Rapporteur urges high -income States to support low-income States in their endeavour to enhance the promotion and protection of the right to health in early childhood, including its developmental dimensions. Obligations of the State in relation to, and responsibilities of, third parties 104. States, as primary duty bearers under international human rights law, are under a duty to protect the right to health by ensuring that the actions of third parties contribute to and do not jeopardize it. 66 For example, States must support and assist, to the maximum their extent of available resources, 67 parents and caregivers to care for children and secure the living conditions necessary for their health and optimal development; and protect child victims of violence and witnesses and investigate and punish those responsible for its occurrence. 105. It is also the obligation of States “to adopt legislation or to take other measures ensuring equal access to health care and health-related services provided by third parties.” 68 In relation to early child development and survival, States should introduce into domestic law, implement and enforce the International Code on Marketing of Breast-milk Substitutes. 69 __________________ 63 64 65 66 67 68 69 22/25 P.
