The centre of the global economy today resides in Asia, not Europe or North America. According to the International Monetary Fund, Asia in 2016 accounted for 40 per cent of global GDP (Lagarde 2016). As Asia also accounts for much of global economic growth in recent years, developments in the region are therefore central to the global economic outlook and for formulating policies around the world (IMF 2015: 1). Asia’s remarkable economic rise is led by China, which had a GDP of around US$11.4 trillion in 2016, making it the second largest economy in the world after the United States. Despite economic stagnation since the 1990s, Japan in 2016 remained the world’s third largest economy, with a GDP of about US$4.7 trillion. Other significant economic powerhouses in Asia include India and South Korea (IMF 2016). The trend is quite clear: Asia is on course to regain the dominant economic position it held before the Industrial Revolution in Europe (ADB n.d.). The maintenance of stability in Asia has therefore become pivotal to global stability; conversely, regional instability will have deep, global consequences. Since the surrender of Japan in 1945 at the end of the Second World War, the United States has been deeply engaged in Asia, and has maintained a form of hegemony over the region, though its failure in the Vietnam War demonstrated the limits of its dominance. The US role has been mostly seen as positive, at least to its allies and the non-communist states in Asia, as it has, through its hubs and spokes system of alliances and military presence, exercised sufficient power to maintain general stability in the region. In turn, this has facilitated Asia’s economic rise (Beeson 2011).
