The concept of the Indo-Pacific as a framework for analysis and policymaking is gaining traction, even as the global center of gravity shifts toward this region. The Indo-Pacific will remain exceptionally dynamic for the foreseeable future and is poised to play a pivotal role in shaping the global geopolitical and economic order. Spanning the Indian and western Pacific Oceans—home to the world’s two fastest-growing regions—the Indo-Pacific is undergoing profound transformations in its geopolitical and geoeconomic landscape. These shifts are driven not only by a rising and increasingly assertive China but also by India and Japan fundamentally redefining their security and defense policies and seeking more prominent regional and global roles. Amid the dual realities of robust economic dynamism and persistent geopolitical uncertainties, a historic opportunity emerges for India and Japan to collaborate closely. As the region transitions from the era of U.S.-led unipolarity, the two nations can work together to promote peace, stability, and sustainable development—helping to build a stable, viable, and enduring regional order.
