In this paper commissioned by the International Commission on Nuclear Nonproliferation and Disarmament, George Perkovich and Patricia Lewis identify possible nuclear disarmament and nonproliferation steps that could take the world in the mid-term to a position from which the latter steps toward abolition of nuclear weapons could be charted.

It is also a realistic approach for nuclear disarmament in that a nuclear-weapon-free world would have another set of dangers than the one we now inhabit. In eliminating nuclear weapons, and therefore reducing the likelihood of a nuclear war, we also, at the same time, wish also to reduce the likelihood of war per se. A more stable world, in which conflict resolution mechanisms can be made to work, in which the threat level against states and peoples is reduced, is going to pave the way for nuclear disarmament and war prevention. Power imbalances will have to be addressed as will other types of security assurances—ones that may indeed provide far greater reassurance than the nuclear umbrella—in which faith has been diminishing significantly since the end of the cold war.

U.S. unpredictability has allowed China to capitalize on its positioning as the “responsible great power”. Paradoxically, the more China wins the perception game, the more likely expectations will rise for Beijing to deliver not just words but to demonstrate with its deeds.

Hanoi and Beijing have long treated each other as distant cousins rather than comrades in arms. That might be changing as both sides draw closer to hedge against uncertainty and America’s erratic behavior.

Across Asia, China is better positioned to withstand energy shocks from the fallout of the Iran war. Its abundant coal capacity can ensure stability in the near term. Yet at the same time, the country’s energy transition away from coal will make it even less vulnerable during the next shock.

In the latest Five-Year Plan, the Chinese president cements the shift to an innovation-driven economy over a consumption-driven one.
