Book excerpt: ?With Western countries consumed by domestic problems, will it be China and Russia that now define the rules of global politics? In a disorderly world, each has become increasingly assertive, and their partnership has emerged from relative obscurity to acquire a new prominence. Yet appearances are deceptive. Beijing and Moscow have shown no capacity to cooperate on grand strategy or establish new international norms. This is no authoritarian alliance, but a partnership of strategic convenience – pragmatic, calculating and constrained.
