This chapter reviews Sweden’s approach to delivering in partner countries and through partnerships to determine whether its approach is in line with the principles of effective development co-operation. Sweden is a highly-valued partner who bases its relationships on dialogue, flexibility and trust, and supports donor co-ordination. It favours long-term partnerships with multilateral organisations and civil society organisations (CSOs), but could expand its partnerships with the private sector and partner country governments. Sweden also struggles to gain a clear overview of its funding in any one country due to its multitude of strategies and could rationalise its funding further to improve effectiveness and oversight.Sweden is committed to the development effectiveness principles, as demonstrated by its partnership approach and its support for partner country ownership and capacity development. However, it struggles to improve performance against some development effectiveness indicators and Sweden could consider establishing criteria to encourage staff to use partner countries systems more and put more aid on budget.
