Indo-Pacific

[12] Some seashore and coastal plants are found throughout most of the region, including the trees Pisonia grandis, Calophyllum inophyllum, Heliotropium arboreum, Pandanus tectorius, Cordia subcordata, Guettarda speciosa, and the shrubs Scaevola taccada, Suriana maritima, and Pemphis acidula.

[22] The trees coconut (Coco nucifera), candlenut (Aleurites moluccanus), and Morinda citrifolia originated in the Central Indo-Pacific, and were spread further across the region by human settlers.

The entrance of the European colonial powers, such as the Dutch and British East India Companies and the Portuguese, and the launch of a trans-Pacific transport of slaves, migrants, and goods, created a deeper Indo-Pacific economic integration.

[4]: 3–22 In the 21st century, with the rising involvement of the United States in the new growth areas of Asia, the idea of the Indo-Pacific Economic Corridor (IPEC) emerged during the U.S.–India Strategic Dialogue of 2013.

The IPEF contains four pillars: Historical precedent for the Indo-Pacific as a politically contested space comes from ancient times; in the European colonial era, commercial interests led to conquest by powers such as the Dutch and British East India Companies throughout the region.

He envisioned an "Indo-Pacific" comprising anticolonial forces in India and China, as Germany's ally against the maritime domination of Britain, the United States, and Western Europe.

[27][28] The focus of Japanese Prime Minister's August 2007 speech in the Indian Parliament was on security of sea lanes linking the two oceans.

In the academic discourse relating to such maritime security issue in the Indo-Pacific, the first articulation was carried by a paper published in January 2007 by the Institute of Defense Studies and Analyses (IDSA), New Delhi.

[30] From about 2011 onwards, the term has been used frequently by strategic analysts and high-level government/military leadership in Australia, Japan and the United States to denote said region.

[31] It is also "symbiotically linked"[5] with the Quadrilateral Security Dialogue—an informal grouping of like-minded democracies in the region, comprising Australia, India, Japan, and the United States.

[32][33] In 2013, Indonesian Foreign Minister Marty Natalegawa proposed an "Indo-Pacific Treaty of Friendship and Cooperation" to restore trust, manage unresolved territory disputes, and help countries deal with change in the region.

In marking 70 years of diplomatic relations between India and the United States, the leaders resolved to expand and deepen the strategic partnership between the countries and advance common objectives.

Above all, these objectives include combatting terrorist threats, promoting stability across the Indo-Pacific region, increasing free and fair trade, and strengthening energy linkages".

[45] According to Dr. Cenk Tamer, the U.S. seeks to create an "anti-China axis" in the Asia-Pacific region through the conceptualization of the Indo-Pacific because it sees India as a key part in containing China.

However, it is also clear that ASEAN does not share the exact same understanding of the term as the US,[49] and its AOIP statement specifically states[46] that it envisions continuing to play a "central and strategic role" in the region.
