I think economic interdependence makes it more likely that Washington and Beijing will make the compromises necessary to negotiate a stable relationship reflecting their changed power relativities. Optimists like Geoff seem to think it makes negotiation and compromise unnecessary. Their confidence in Adam Smith and Immanuel Kant provides an agreeable illusion that the invisible hand will keep the peace, so politicians do not have to bother. And that makes it less likely that they will make the compromises necessary to avoid escalating rivalry, and hence more likely that the rivalry will indeed escalate.
