What It Means in Practice
The 'Indo-Pacific' is a geopolitical concept treating the Indian and Pacific Oceans as a single integrated strategic theater, distinct from the older 'Asia-Pacific' framing centered on East Asia. The conceptual move integrates the Indian Ocean (and India's role) into US strategic thinking, displacing the Cold War-era 'Asia-Pacific' that centered on China-Japan-US relations.
The Indo-Pacific framing emerged in the 2010s, popularized by Japanese Prime Minister Shinzo Abe's 2007 'Confluence of the Two Seas' speech to the Indian parliament. The framing was adopted by the US under Trump (the 2017 National Security Strategy formally replaced 'Asia-Pacific' with 'Indo-Pacific'), then deepened under Biden. It has since been adopted by Australia, India, France, the UK, the EU, Germany, and the Netherlands, each producing their own Indo-Pacific strategy document.
Why It Matters
The Indo-Pacific framing is strategic vocabulary doing geopolitical work. It expands the region's mental geography to include the Indian Ocean, which means including India as a structural strategic partner. It reframes maritime law issues (especially the South China Sea) as central to regional order. It implicitly treats China's rise as a strategic problem requiring coordinated response.
The framing is implicitly anti-China. 'Free and Open Indo-Pacific' (FOIP), the standard formulation, signals support for maritime law (read: against Chinese claims in the South China Sea), , and an alternative to BRI infrastructure financing. China has rejected the framing as a 'Cold War mentality' and has not adopted it.
Indo-Pacific vs Asia-Pacific
The two framings differ in three structural ways:
- Geography: Asia-Pacific centers on the Pacific Rim from Japan/Korea to Southeast Asia and Australia. Indo-Pacific extends into the Indian Ocean to include India, Sri Lanka, Madagascar, and the East African coast.
- Strategic logic: Asia-Pacific was the Cold War-era framing of US trans-Pacific alliances. Indo-Pacific is the 21st-century framing of China-balancing maritime cooperation.
- India's role: Asia-Pacific treats India as peripheral; Indo-Pacific puts India at the center.
The ASEAN response, the ASEAN Outlook on the Indo-Pacific (AOIP) released in 2019, accepts the framing while emphasizing inclusivity and ASEAN centrality. ASEAN does not endorse the explicit China-balancing element of US Indo-Pacific strategy.
Institutional Manifestations
The Indo-Pacific framing has produced several institutional structures:
- Quad — the US-Japan-Australia-India strategic forum.
- — the trilateral defense-technology partnership.
- Indo-Pacific Economic () — the US-led economic engagement framework.
- PBP (Partners in the Blue Pacific) — US-allied Pacific Islands cooperation.
- US INDOPACOM — the renamed combatant command (previously PACOM) reflecting the strategic shift.
Common Misconceptions
The Indo-Pacific framing is not exclusively a US construct. Japan, Australia, and India have each developed their own Indo-Pacific strategies, with substantive policy differences from the US version. The Indian and Japanese versions emphasize economic cooperation and inclusivity more than the US version.
Another misconception is that the framing has fully displaced 'Asia-Pacific.' Both are in use — 'Asia-Pacific' continues in trade contexts (APEC, ) while 'Indo-Pacific' dominates security and strategic vocabulary.
Real-World Examples
The 2017 US National Security Strategy formally adopted 'Indo-Pacific' — the first major doctrinal use. France's Indo-Pacific Strategy (2018) and Germany's Indo-Pacific Guidelines (2020) demonstrated European adoption. India's and the Indo-Pacific Oceans (announced by PM Modi at the 2019 East Asia Summit) are Indian articulations of the framing. ASEAN's AOIP (2019) is the regional grouping's attempt to engage with the framing while preserving its own centrality.
Example
The Pentagon's 2018 reorganization of US Pacific Command into US Indo-Pacific Command formalized the geographic concept in US military structure.
