Creating an institutional framework on a global scale to understand balance-of-power strategies is the crux of foreign policy today with United States superpower exceptionalism. ‘Altercating’ defence, diplomacy and development encapsulate the United States foreign policy in relation to national interests globally. Role theory applied in comparing the United States and Chinese grand strategies as case studies. The United States superpower statecraft’s clarity help superimposed any form of countervailing alliances globally; while China’s sociological pragmatist role currently could change based on ‘Power Transition Theory’ for hegemony power. Beijing is pursuing a grand strategy that combines both ‘internal balancing’ and external ‘soft balancing’, encapsulated as ‘warfare ecosystem construct’ as countervailing alliances for balance-of-power strategies with development of ‘Economic Corridors’ in East Asia ; and the United States ‘Globalization Agenda’ both executed as ‘mechanisms of power’ date back to their ‘hegemonic histories’ with adaptive construct for national interests.
