The international system during the past few decades has witnessed the steady rise of China as a new great power and game-changer. For over a century the United States has possessed the world's largest economy, but at present trajectories, China may replace it during the first half of the century and emerge as the leading economy of the world. China’s economic growth has also fueled a rapid modernization of its armed forces enabling Beijing to assert its presence more bluntly in areas of dispute especially in the Taiwan Strait and the south china sea. China’s territory size, population, Geography, vibrant economy, relative stability and growing military capabilities have all helped it to confidently elevate its international standing with improved geopolitical status enabling Beijing to establish itself as a decisive player in global affairs.
