What or where is the Indo-Pacific? How a foreign policy pivot redefined the global map
By Andrew Latham
Open a book of maps and look for the 'Indo-Pacific' region – it likely won't be there.
Yet the Indo-Pacific is now central to how many countries think about strategy and security. It describes a region spanning two oceans and dozens of countries, encompassing much of the world's trade routes.
The Indo-Pacific did not emerge from the patterns of ancient trade, nor from long-standing cultural or civilizational ties.
Instead, the concept comes from the realms of political science and international relations. The term can be traced back to the work of German political scientist and geographer Karl Haushofer – a favorite of Adolf Hitler – in the 1920s. But it only really began to take hold in the think tanks and foreign policy-setting departments of Washington and other Western capitals in the late 20th and early 21st centuries.
It coincided with a shift in the global balance of power from unipolarity – that is, dominated by one superpower – to multipolarity over the past decade or so.
'Confluence of the two seas'
For much of the Cold War, the United States treated the Pacific and Indian oceans as separate theaters of operation. Its military forces in the area, known as U.S. Pacific Command, focused on East Asia and the western Pacific, while the Indian Ocean figured mainly in energy security discussions, tied to the Middle East and the flow of oil through the Strait of Hormuz, which connects the Persian Gulf to the Arabian Sea.
Strategic maps during that era divided the world into distinct zones of interest. But China's economic rise, India's growing influence and the increasing strategic significance of sea lanes across both oceans since the end of the Cold War blurred those old dividing lines.
The Indian Ocean could no longer be treated as a secondary concern. Nor could the Pacific be thought of in isolation from what was happening further west.
Japan helped give political voice to this emerging reality. In 2007, Prime Minister Shinzo Abe stood before India's parliament and spoke of the 'confluence of the two seas' − an image that deliberately linked the Indian and Pacific oceans as a single geopolitical space.
Abe's message was clear: The fate of the Pacific and Indian oceans would be increasingly intertwined, and democratic states would need to work together to preserve stability. His vision resonated in Washington, Canberra and New Delhi, and it helped set the stage for the revival of the Quadrilateral Security Dialogue, or Quad.
In 2018, the United States made the shift official, renaming U.S. Pacific Command as U.S. Indo-Pacific Command.
What might have seemed like a bureaucratic rebranding was in fact a serious strategic move. It reflected the growing recognition that the rise of China − and Beijing's growing influence from East Africato the South Pacific − required an integrated regional approach.
Framing the challenge in Indo-Pacific terms allowed Washington to strengthen its ties with India, deepen cooperation with Australia and Japan, and reposition itself as a maritime balancer across a vast strategic arc.
The phrase 'free and open Indo-Pacific' quickly became the centerpiece of American regional diplomacy. It emphasized freedom of navigation, respect for international law, and democratic solidarity.
But while the rhetoric stressed inclusivity and shared values, the driving force behind the concept was clear: managing China's expanding power. The Indo-Pacific framework allowed Washington to draw together a range of initiatives under a single banner, all aimed at reinforcing a rules-based order at a time when Beijing was testing its limits.
Rejecting zero-sum thinking
Not every country has enthusiastically embraced this vision. Many Southeast Asian states, wary of being drawn into a competition between the United States and China, have approached the Indo-Pacific concept with caution. The Association of Southeast Asian Nations' document titled Outlook on the Indo-Pacific, released in 2019, deliberately avoided framing the region in confrontational terms. Instead, it stressed dialogue and the centrality of Southeast Asia − a subtle rebuke to visions that seemed to pit democracy against authoritarianism in stark, zero-sum terms.
The breadth of the Indo-Pacific concept also raises difficult questions. It covers an enormous range of political, economic and security realities. The priorities of small island states in the Pacific differ sharply from those of major continental powers such as India or Australia. Treating the Indo-Pacific as a single strategic space risks flattening these differences and could alienate smaller nations whose concerns do not always align with those of the major players.
The Indo-Pacific today
Recent shifts in Washington's foreign policy also complicate matters. The Trump administration's skepticism toward alliances created doubts among regional partners about the reliability of U.S. commitments. Even as the Indo-Pacific idea gained traction, questions remained about whether it represented a long-term strategy or a short-term tactical adjustment.
The Biden administration maintained the Indo-Pacific framework, launching the Indo-Pacific Economic Framework for Prosperity to provide an economic counterpart to the security-heavy focus of earlier years. But the central strategic challenge remains the same: how to manage China's rise without forcing the region into a rigid geopolitical divide.
For now, the Indo-Pacific framing has reshaped how policymakers, military planners and diplomats think about Asia's future. It provides a vocabulary for coordinating alliances, building new partnerships and addressing the challenges posed by China's expanding influence.
Yet its long-term success will depend on whether the framework can genuinely accommodate the region's diversity − and whether it can be seen as something more than just a mechanism for great power competition and a thinly veiled strategy to contain China.

India PM Modi eyes visit to Japan in August for bullet train deal
KYODO NEWS - 2 hours ago - 19:11 | All, World, Japan The Japanese and Indian governments are arranging for Indian Prime Minister Narendra Modi to visit Japan in late August for talks with Prime Minister Shigeru Ishiba, diplomatic sources said Saturday. The two leaders are expected to agree on India's adoption of a next-generation shinkansen bullet train being developed by East Japan Railway Co. for a high-speed rail project underway in western India, the sources said. They may also agree to revise the 2008 Joint Declaration on Security Cooperation to expand their security partnership amid China's increasing maritime prowess, they said. The visit would be Modi's first since May 2023, when he attended the Group of Seven summit in Hiroshima, western Japan. Modi and Ishiba also aim to strengthen communication ahead of a four-way summit with the United States and Australia under the Quad framework, which New Delhi is set to host in the fall. The high-speed rail line will connect the western Indian cities of Ahmedabad and Mumbai, covering about 500 kilometers in roughly two hours. The project is considered a symbol of Japan-India cooperation, as it will use Japan's renowned shinkansen technology. JR East aims to complete the E10 series carriages in the fall of 2027 at the earliest, with commercial operation starting in fiscal 2030. In their meeting, Modi and Ishiba are expected to confirm plans to introduce the E10 series in the early 2030s, according to the sources. Through the revised security declaration, the two sides are expected to agree on strengthening comprehensive cooperation in broader areas, including space and cybersecurity, the sources said.

Modi coming in August to seal deal on bullet trains for India
India's Prime Minister Narendra Modi reviews the honor guard at the Government House in Bangkok on April 3. (Reuters) Japanese and Indian officials are putting the final touches on a trip to Japan in late August by Indian Prime Minister Narendra Modi that will see Tokyo reaping a windfall sale of the latest Shinkansen bullet train technology to New Delhi. East Japan Railway Co. is planning to start commercial operations of its new E10 series of bullet trains in fiscal 2030, which the government has already said it is willing to share with India, according to several diplomatic sources in the two nations. 'This would be the first case of the latest model being introduced simultaneously in Japan and another country,' said a government source in Tokyo. During Modi's visit in late 2015 when Shinzo Abe was prime minister, it was agreed that India's first high-speed railway network would use Japanese technology. Initially, the E5 series used on the Tohoku Shinkansen line was to be exported to India. But then JR East in March announced plans to begin development of the next-generation E10 series of bullet trains, so officials approached their Indian counterparts about using that technology instead, according to sources. Modi last visited Japan in May 2023 as one of the invited leaders to join the Group of Seven summit in Hiroshima. One aim of the August trip is to set a pattern of reciprocal visits by the leaders of the two nations. India will host the Quadrilateral Security Dialogue, known as the Quad meeting, that groups Australia, India, Japan and the United States this autumn. Prime Minister Shigeru Ishiba is expected to attend. Arrangements are now being worked out for Modi and Ishiba in August to visit the plant in Miyagi Prefecture where the E10 prototype is being developed. Modi will also get an update on a plan announced in 2022 by Ishiba's predecessor, Fumio Kishida, for Japan to invest 5 trillion yen ($34.2 billion) in India over a five-year period. The two leaders are also expected to discuss cooperation in constructing a supply chain for semiconductors and other vital products. Modi may visit China after his Japan trip to attend the Shanghai Cooperation Organization summit, according to diplomatic sources. Russia is also a member of that organization. By visiting Japan prior to China, Modi will alleviate concerns in Tokyo that New Delhi, with its longstanding nonaligned diplomatic policy, is too dependent on Beijing, a government source said.
