Global health is determined by factors which themselves often show scant respect for national boundaries – such as international trade, climate change, pollution, confl ict, environmental degradation and poverty. The UK Government cannot achieve the ambition set out in this strategy alone. Because so many sectors affect health, and so many countries and agencies are involved in healthcare, improving health around the world requires co-operative actions and solutions. This means creative, joined-up partnership both between UK government departments, and between the UK Government and a host of other partners, ranging from the EU and the UN to non-governmental organisations (NGOs), foundations, academia and business.
