Amid the spectre of superpower confrontation, Fumio Kishida warned that for the first time since the height of the Cold War, the momentum towards a world without nuclear arms was on the verge of reversal.

Tensions have been soaring on the Korean peninsula, in the South and East China seas and across the Taiwan Strait, with the emergence of two opposing cold war-style camps: one led by Washington and the other by Beijing.
In a “seismic shift” in the regional security landscape, China, Russia and North Korea have inched closer to counter the US, prompting growing calls in Japan and South Korea for the two countries to acquire their own nuclear weapons to fend off a potential axis of nuclear-armed authoritarian regimes.
