Background
Strategic framework of US–China competition
In the early twenty-first century, the strategic preoccupation of the United States with Iraq and Afghanistan served as a distraction from major power shifts in the
Asia-Pacific, brought about by increased
Chinese economic power, which undermined America's traditional role in the region.

List of Leaders Summits
Creation and cessation of the Quad (2007–2008)
Creation
In early 2007, Prime Minister Abe proposed the Quad, under which India would join a formal multilateral dialogue with Japan, the United States and Australia.
The initiation of an American, Japanese, Australian and Indian defence arrangement, modelled on the concept of a
Democratic Peace, was credited to Japanese Prime Minister Shinzo Abe.
[Chellaney, Brahma]
"Different playbooks aimed at balancing Asia’s powers"
''The Japan Times'', 3 November 2008 (originally published by the BBC Monitoring South Asia). The Quad was supposed to establish an "Asian Arc of Democracy", envisioned to ultimately include countries in Central Asia, Mongolia, the Korean Peninsula, and other countries in Southeast Asia: "virtually all the countries on China’s periphery, except for China itself." This led some critics, such as former
U.S. State Department official
Morton Abramowitz, to call the project "an anti-Chinese move", while others have called it a "democratic challenge" to the projected Chinese century, mounted by Asian powers in coordination with the United States. While China has traditionally favoured the

These were followed in October by a further security agreement between Japan and India, ratified during a visit by Indian Prime Minister Manmohan Singh to Tokyo, to promote sea lane safety and defence collaboration; Japan had previously established such an agreement only with Australia.
Though the Quadrilateral initiative of the
Bush administration improved relationships with New Delhi, it gave the impression of "encircling" China.
The security agreement between Japan and India furthermore made China conspicuous as absent on the list of Japan's strategic partners in Asia.
These moves appeared to "institutionally alienate" China, the
Association of South-East Asian Nations (ASEAN), and promote a "Washington-centric" ring of alliances in Asia.

Taro Aso, downplayed the importance of China in the Japan-India pact signed following the creation of the Quad, stating, "There was mention of China – and we do not have any assumption of a third country as a target such as China." Indian Foreign Secretary

to India on the basis of similar considerations, as it appeared that the United States was backing it as a "counter to a rising China." Chinese anger over the Quad however caused uneasiness within Australia even before the agreements were initiated.
On becoming Prime Minister, Kevin Rudd visited China's foreign minister,
Yang Jiechi, even before visiting Japan, and subsequently organized a meeting between Yang and the Australian foreign minister,
Stephen Smith, in which Australia unilaterally announced it would "not be proposing" a second round of dialogue between the four partners.
[Gordon, Josh]
"Diabolical dilemmas in PM’s China high-wire act"
''Sunday Age'', 5 April 2009. Within Australia, this decision was seen as motivated by the uncertainty of
China-United States relations and by the fact that Australia's principal economic partner, China, was not its principal strategic partner. Rudd may furthermore have feared regional escalations in conflict and attempted to diffuse these via an "Asia-Pacific Union."

Rudd's calculation may have been that as a regional economic power, China was too important to contain through a simplistic Quadrilateral Initiative undertaken by US, India, Japan and Australia in 2007, when many regional powers are hedging their alliances in the event of a Japanese and an
American decline.

Xi's political program calls for a China more united and
confident of its own value system and political structure.
Under
Xi's leadership, the PRC has resorted to island building in the Spratly Islands and the Paracel Islands region.
According to Reuters, island building in the South China Sea primarily by Vietnam and the Philippines has been going on for decades; while China has come late to the island building game, its efforts have been on an unprecedented scale as it had from 2014 to 2016 constructed more new island surface than all other nations have constructed throughout history and as of 2016 placed military equipment on one of its artificial islands unlike the other claimants. A 2019 article in Voice of America that compared China and Vietnam's island building campaign in the South China Sea similarly noted that the reason why Vietnam in contradistinction to China has been subject to little international criticism and even support was because of the slower speed and widely perceived defensive nature of its island-building project.

India's shift in position and "Act East"
In the years following the cessation of the Quad, India was not keen to reinstate the grouping, out of fear it would antagonize China.
After several years of growing tensions with China on a range of topics, and particularly after the
2017 border standoff, India started to express renewed interest.

In December 2020, in an online meeting between Japan's and Germany's defence ministers, Japan expressed hopes for Germany to send a warship to the Indo-Pacific region, and join drills with Japan Self-Defense Forces, In March 2021, Germany confirmed that it would send a frigate in August to the South China Sea, making it the first German warship since 2002 to traverse the region.

Netherlands
In November 2020, the Netherlands published its Indo-Pacific strategy, making it the third EU member to do so, following France and Germany.
The policy document calls on the EU to build partnerships in the region and to reject Chinese territorial claims more strongly. As part of this policy shift, the Netherlands would send the frigate
HNLMS Evertsen to the Indo-Pacific as part of the British aircraft carrier group in 2021. In April 2021, Dutch prime minister
Rutte and Indian prime minister Modi held a videoconference meeting to discuss cooperation in the Indo-Pacific region.

Analysis
According to the American think tank
Center for a New American Security (CNAS), the United States pursued the Quad in an effort to adapt to an increasingly economically powerful China in the Asia-Pacific, where great power rivalry, massive military investment, social inequality, and contemporary territorial disputes have all made war in Asia "plausible."
According to the CNAS, establishing a series of alliances among nations recognized as democratic by the United States furthers its own interests: "It is precisely because of the rise of Chinese power and the longer term trend towards multipolarity in the international system that values can and should serve as a tool of American statecraft today."

According to academic Jeremy Garlick, publishing in early 2024, the Quad had not yet achieved much in practice.
Academic Jeffrey Crean concludes that as of 2024, the Quad had yet to find common ground or a coherent strategic approach.
Crean writes that while Quad members have various conflicts with China, those conflicts arise in significantly different areas or with regard to different issues and this has been an obstacle to unified action.
