These guidelines are a first step to support UNDP staff in delivering UNDP’s renewed offer on South-South and Triangular Cooperation to our government counterparts. This type of support is recommended in UNDP’s Strategic Plan and UNDP’s South-South Corporate Strategy. The guidelines cover key technical steps to consider when developing and implementing national SouthSouth Cooperation (SSC) policies, which can lead to the establishment of the broader national SSC institutional and policy architecture, as recommended in BAPA+40 outcome document. These guidelines are not intended to be definitive, but rather to be flexible, adaptable to national priorities and understandings and non-linear. They are intended to support countries that wish to become active partners of SSC and build on the momentum generated by BAPA+40. They are focussed primarily on technical SSC rather than economic cooperation or trade.
