Entente cordiale
The UK is a permanent member of the United Nations Security Council, a member of NATO, the Commonwealth of Nations, the G7 finance ministers, the G7 forum, the G20, the OECD, the WTO, the Council of Europe and the OSCE. The UK is said to have a "Special Relationship" with the United States and a close partnership with France – the "Entente cordiale" – and shares nuclear weapons technology with both countries; the Anglo-Portuguese Alliance is considered to be the oldest binding military alliance in the world. The UK is also closely linked with the Republic of Ireland; the two countries share a Common Travel Area and co-operate through the British-Irish Intergovernmental Conference and the British-Irish Council. Britain's global presence and influence is further amplified through its trading relations, foreign investments, official development assistance and military engagements. Canada, Australia and New Zealand, all of which are former colonies of the British Empire, are the most favourably viewed countries in the world by British people.
