Triangular cooperation (TrC) is a modality of international development cooperation through which jointly planned, financed and implemented projects are supported: Typically, it involves collaborations between a facilitator, a pivotal partner, and one (or more) beneficiary partner(s). TrC combines experience and expertise, as well as financial, institutional, and human resources, and can strengthen trust and horizontal relationships among participating countries. Developmental impact is achieved by combining the complementary strengths of each partner and a multi-stakeholder approach.
