Partner countries are the leaders of development planning and implementation process. Ownership of the development co-operation process by partner countries is crucial for increased effectiveness and impact and to ensure collective action to accelerate progress and achieve national objectives and the Sustainable Development Goals. In line with the agreed effective development co-operation principles, partner governments use nationally-owned development co-operation policies and other country frameworks to illuminate their own development priorities; ensure an enabling environment for the participation of civil society, the private sector and other stakeholders; and provide an inclusive platform to harness the comparative advantages of all partners and promote accountability for better development results.
