What are the strategic implications of rapid economic development in Asia? History shows that countries undergoing rapid economic growth experience a transformation in their perceptions of their opportunities and vulnerabilities; and that near simultaneous changes in security perceptions among several countries in the same region results in substantial strategic churn.In this lecture, Michael Wesley from the National Security College explores some of the political implications of economic growth among Asia's "southern tier". He considers these changes in the context of maritime Asia's strategic geography to forecast six key areas of instability and competition in the Indo-Pacific in the century ahead. He concludes by drawing out some lessons for Australian foreign and defence policy.One of Australia's leading international relations experts, Professor Michael Wesley, joined the National Security College as Director: Academic, Outreach & Research in 2012. Professor Wesley has extensive experience teaching, researching and communicating on Australia's international engagements, particularly in Asia. He has also published extensively and won the 2011 John Button Prize for Best Writing in Australian Politics for his book "There Goes the Neighbourhood: Australia and the Rise of Asia".
