Following a historic meeting between the leaders of the United States, Japan and the Republic of Korea at Camp David in August, the three countries have been strengthening military and intelligence cooperation.  What does it mean for the balance of power in Asia? Could this lead to an escalation of tensions with China and North Korea? And crucially, can the "trilateral partnership" last, given the difficult history between Japan and South Korea? In this episode, CSDS-Asia Matters' Andrew Peaple interviews Tongfi Kim, from the Centre for Security, Diplomacy and Strategy at the Brussels School of Governance, and Mayumi Fukushima, a researcher at Harvard University's Belfer Center for Science and International Affairs.
