  • to launch a Foreign Minister-led “Strategic Dialogue” with a view to sharing assessments and strategic views on the regional and international environment;
  • to start negotiations on a government to government information security agreement;
  • to endorse Defence Ministers signing the Defence Cooperation Memorandum at the next opportunity;
  • to build on the signature of this Memorandum and defence engagement, such as in research collaboration, by identifying new areas of cooperation;
  • to identify a range of appropriate defence equipment for joint development and production, that can be carried out in accordance with Japan’s 2011 Guidelines for Overseas Transfer of Defence Equipment etc. which contributes to both countries’ security and presents industrial opportunities;
  • to seek to launch at least one programme of such defence equipment as soon as possible and explore the feasibility of a future major programme that will also contribute to both our countries’ security and peaceful intent;
  • to consider appropriate government-to-government arrangements which will ensure strict control on third country transfer and on extra-purpose use of defence equipment; and
  • to explore ways to further strengthen our security and defence cooperation, including joint exercises, training and unit to unit affiliations.
