Japan and Australia have solidified their military partnership amidst rising tensions due to China's military assertiveness in the Indo-Pacific, particularly following recent Chinese incursions into Japanese airspace and territorial waters. During a meeting in Queenscliff, the foreign and defense ministers from both nations agreed to enhance joint military training exercises, including plans for Japan to participate in U.S. Marine rotations in northern Australia. This collaboration aims to improve air force engagement and counter China's aggressive territorial claims in the South and East China Seas, as expressed by both nations' officials. The ministers emphasized their commitment to a rules-based international order and the necessity of closer security ties in the face of evolving regional threats. Japan's increased military cooperation will include sending a liaison officer to Australia in late 2024, signifying a deeper strategic alliance. Both countries are determined to advance their defense collaboration while navigating the complex geopolitical landscape shaped by China's actions.
