Nuclear competition has been on the rise in Asia, with competition and confrontation among major nuclear powers around regional issues ranging from territorial disputes (from Kashmir to the South China Sea), conventional arms build-ups, the testing and deployment of ever more effective offensive missile systems, the installation of anti-ballistic missile systems (notably the deployment of THAAD on the Korean peninsula), and the continued nuclear provocations of nuclear tests by the DPRK. Against this background, how do the non-nuclear weapon states with advanced nuclear capabilities resist the temptation to develop nuclear weapons? And what can innocent bystanders in ASEAN and elsewhere do to help reduce tensions and thereby reduce the risk of collateral harm from the posturing of others? This session proposes ways to prevent the domino effect of nuclear armament in the region and the roles of non-nuclear-armed countries can play in reducing nuclear threats.
