We need a public diplomacy which fits our time. The policy issues which confront us are increasingly global. Systematic engagement with publics both at home and abroad will be required if we are to identify and implement solutions. Policy-makers and diplomats must work with a wider range of constituencies beyond government, moving towards a more open, inclusive style of policy-making and implementation. Understanding of complexity, difference, networks and cultural heritage will be needed, alongside more imaginative use of technology. Engagement, conducted with energy, ambition and creativity, must be the hallmark of contemporary public diplomacy.
