At the ROK-Australia summit, held on the sidelines of the G7 summit, President Yoon Suk Yeol pledged to ramp up efforts to advance defense and global supply chain cooperation as one of the like-minded regional players in the Indo-Pacific that share democratic values by strengthening regional cooperation in the defense and space industries and increasing joint military exercises. And at the ROK-India summit, President Yoon vowed to deepen cooperation with India in the defense, digital, bio-health, and space industries, and to expand cooperation in the defense industry with Germany and Indonesia. As it is forecast that the Korean government will endeavor to facilitate defense and high-tech cooperation with like-minded countries in the region, its military diplomacy needs to be formulated and implemented in a way that advances Korea’s military and economic interests to improve Korea’s standing in the Indo-Pacific by joining regional efforts to establish a robust rules-based international order in the region.
