The future of American leadership in the Asia-Pacific under the Trump administration appears uncertain. In this timely book, Michael Heazle and Andrew O’Neil have brought together contributors from across the globe to explore the commitment of Australia and Japan to US leadership in this region, and how this commitment may impact on often tense relations between China and the US. China's Rise and Australia?Japan?US Relations discusses the strategic post-war presence of American leadership in Asia, and examines the influence on the region’s geopolitics. This book allows readers to understand how and why China is challenging this external engagement, and conversely why Australia and Japan want to maintain a commitment to US input; their perceptions of American leadership are critical indicators of the prospects for change in the region. This is a vital book for security and international relations scholars, researchers and experts, as it provides detailed analyses of current relations between countries in the Asia Pacific and the US, as well as giving a thorough look into what the future is likely to hold in terms of US commitment in the region.
