In 12 out of 16 cases in the past 500 years when a major rising power “disrupted the position of a dominant state” the contest ended in war according to Graham Allison’s recent study. Clearly, the historical odds of a harmonious US-China power transition are not very high. But this is not just a typical relationship. One challenge in studying US-China relations is that both sides, for a variety of reasons, feel compelled to often obscure their parallel interests. For Beijing, the reasons are linked to both its state identity and legitimacy around China’s standing in the developing world. The Chinese cannot exude a G-2 posture beyond a certain point without incurring real costs to its international status and domestic political stability. For Washington, an overt cooperative posture could unravel its Asian alliances by provoking fears of abandonment as well as complicate the aim of deepening ties with China’s other neighbours since much of that engagement is sold on the premise of US-China antagonism.
