“Goodbye G7, hello G20.” That was the headline on an article in The Economist on the first summit of the Group of 20 in Washington in 2008 which argued that this represented “a decisive shift in the old order”. Today, hopes of a co-operative global economic order, which reached their zenith at the G20’s London summit of April 2009, have evaporated. Yet it is hardly a case of “Goodbye G20, hello G7”. The earlier world of G7 domination is even more remote than that of G20 co-operation. Neither global co-operation nor western domination look feasible. What might follow? Alas, “division” might be one answer and “anarchy” another.

That is not what the communiqué from the meeting of G7 heads of government in Hiroshima suggests. It is breathtakingly comprehensive. It covers: Ukraine; disarmament and non-proliferation; the Indo-Pacific region; the global economy; climate change; the environment; energy, including clean energy; economic resilience and economic security; trade; food security; health; labour; education; digital; science and technology; gender; human rights, refugees, migration and democracy; terrorism, violent extremism and transnational organised crime; and relations with China, Afghanistan and Iran (among other countries).

At 19,000 words, this reads like a manifesto for a world government. In contrast, the communiqué of the London G20 summit in April 2009 was just over 3,000 words. This comparison is unfair, given the focus at that time on the economic crisis. But an unfocused wish list cannot be useful: when everything is a priority, nothing is.
