What is triangular co-operation?

One innovative, promising way of expanding global co-operation for sustainable development

Triangular co-operation helps to achieve the SDGs in innovative and collaborative ways and can provide solutions to overcome today's most pressing environmental, economic and social challenges, ensuring sustainable development in partner countries.

At the OECD we see the combination of three roles, which may revolve throughout the implementation of the initiative, as the common denominator in triangular initiatives:

  • The beneficiary partner seeks support to tackle a specific development challenge;
  • The pivotal partner has proven experience in the issue, and shares its resources, knowledge and expertise;
  • The facilitating partner helps connect the beneficiary and the pivotal partners, supporting their collaboration financially and technically.

 The roles may change throughout the life of a project.

  • There can be several actors at each edge of the triangle.
  • Those actors may be representing countries, international organisations, civil society, private sector, trade unions or private philanthrophy.
