The aim of this paper is to project China's emerging path towards high politics in East Asia, which is ostensibly spawned by regional geopolitical dynamics. Hegemonic transition, replacing hegemonic stability, is seemingly activating the dynamics. There is almost an inexorable move towards predominance, by the two major powers, that tends to get stimulated by the presence of issues that may trigger conflict, possibly war. These issues range from flashpoints to populist nationalism, economic interdependence, nuclear issues, and alliance relations in the Western Pacific. The paper concludes, by highlighting, likely resultant action–reaction cycles, polarizations, and alignments through the varying array of forces, possibility of war, mutual deterrence, and above all projecting overall power relations.
