The methods that States parties use to fulfil the obligations they have assumed under the Covenant in respect of older persons will be basically the same as those for the fulfilment of other obligations (see General Comment No. 1 (1989)). They include the need to determine the nature and scope of problems within a State through regular monitoring, the need to adopt properly designed policies and programmes to meet requirements, the need to enact legislation when necessary and to eliminate any discriminatory legislation, and the need to ensure the relevant budget support or, as appropriate, to request international cooperation. In the latter connection, international cooperation in accordance with articles 22 and 23 of the Covenant may be a particularly important way of enabling some developing countries to fulfil their obligations under the Covenant.
