Both America and China have blinked in their dispute over the renminbi's exchange rate. A fortnight before Tim Geithner was due to pronounce on whether China manipulates its currency, the US Treasury secretary postponed the report. The decision followed President Hu Jintao's announcement that he would attend this week's US-led nuclear disarmament summit for forthright discussions on imposing new sanctions on Iran and curbing North Korea's nuclear weapons programme.

Although putting the renminbi on the back-burner serves the interests of both Washington and Beijing, the world's response to the debate suggests the dangers of such brinksmanship. America received almost no support for its tough stance, save for some mild words of rebuke from Dominique Strauss-Kahn, the managing director of the International Monetary Fund, and a soft joint letter of protest from five leaders of the Group of 20. There was a deafening silence from Japan and South Korea, both of which have massive investments in China. Their most powerful companies' profits are linked to China's export success, which a stronger renminbi would undermine.

But Beijing should not take comfort from this because its neighbours are increasingly jittery about Chinese power. Evidence can be found in India's efforts not only to forge an alliance with the US but, during Vladimir Putin's recent visit, to revive military ties with Russia. A call from Yuriko Koike, the former Japanese defence minister, for a strengthening of Japanese-Indian military ties also suggests that the region's powers are looking for ways to contain China.
