The financing agreement was formalised during the Oceans Conference in Malta this week.
Under the agreement, which is financed through the 11th European Development Fund, the EU will provide $US1.65 million dollars to the Cook Islands' budget to help with the implementation of the National Sustainable Development Plan and the Sanitation Policy over the next four years.
