The Quad grouping on Tuesday widened cooperation in the critical minerals and energy sectors and introduced new steps to improve maritime surveillance and port infrastructure across the Indo-Pacific.
The move comes against the backdrop of China's expanding military presence in the region.
The new measures were announced following a meeting of the grouping's foreign ministers in New Delhi, chaired by External Affairs Minister S Jaishankar attended by US Secretary of State Marco Rubio, Australian Foreign Minister Penny Wong, and Japanese Foreign Minister Toshimitsu Motegi.
"We affirm our support for a free and open Indo-Pacific that allows countries to develop resilience and strengthen capacity to determine their own paths. To that end, we concur on further enhancing cooperation and advancing concrete initiatives to deliver tangible benefits to the region," the ministers said in a joint statement.
The Quad foreign ministers also called for an uninterrupted flow of global commerce through the Strait of Hormuz, criticised Iran's imposition of tolls on commercial shipping in the region and voiced serious concern over the situation in the East China Sea and the South China Sea.
"We reiterate our strong opposition to any destabilising or unilateral actions, including by force or coercion, that threaten peace and stability in the region," the ministers also said in the statement, sending a message to China.
"We express our serious concerns regarding dangerous and coercive actions, including interference with offshore resource development, the repeated obstruction of freedom of navigation and overflight, and the dangerous manoeuvres by military aircraft and coast guard and maritime militia vessels," they said.
"We are seriously concerned by the militarisation of disputed features," they added.
In his media statement, Jaishankar announced a critical minerals framework an Indo-Pacific energy security initiative under broader Quad agenda to confront major challenges facing the region.
"Much of the discussions and indeed the bilateral exchanges were devoted to the current state of the world," Jaishankar said at the end of the meeting.
"Naturally, the focus of the deliberations was on issues of relevance to the Indo-Pacific," he said.
"Because we are four maritime democracies located at different ends of the Indo-Pacific, the exchange of perspectives was an exercise of considerable value. We spent some time on the question of safe and unimpeded maritime commerce and reaffirmed the significance of scrupulously observing international law," he said.
Jaishankar said a free and open Indo-Pacific has many dimensions and facets and the Quad meeting took stock of the progress in many of them.
We believe strongly that economic resilience should be promoted and supply chains should be strengthened, he noted, adding the deliberations also touched upon current energy and fertiliser availability and that of critical minerals.
"In the coming days, whether it is economic activity, energy trade or maritime commerce, the Indo-Pacific will become even more important to the world. The responsibilities of the Quad will grow commensurately, and we must prepare for that," he said.
The external affairs minister said countering common threat of terrorism also figured in the talks.
"There must be zero tolerance for terrorism, and nations subject to terrorist attacks have the right to defend themselves," he said.
In his media statement, Rubio said the Quad meeting decided to launch an Indo-Pacific Maritime Surveillance Cooperation Initiative It will leverage each of our country's maritime surveillance capabilities in the Indo-Pacific, he said.
Rubio also announced the expansion of the Indo-Pacific Maritime Domain Awareness Initiative among the Quad nations.
The US Secretary of State also said the Quad has decided to roll out a new initiative to boost port infrastructure in the Pacific Islands.
"The reason why maritime security is so important, beyond the fact that current events remind us of what can happen when maritime security is impeded, is the fact that 60 per cent of global maritime trade passes through the Indo-Pacific," Rubio said.
He argued that it is a vital national interest not just to the four Quad countries but to countless countries around the world.
"The second initiative: we're going to be partnering on issues of port infrastructure, in response to insufficient port capacities in the Pacific Islands," he said.
"We're announcing plans to work with Fiji to advance that country's port infrastructure. It'll be the first time that the Quad partners work together on a port infrastructure project," he said.
The Australian Foreign Minister said the Quad recognised efforts towards a diplomatic resolution to ensure freedom of navigation in the Strait of Hormuz.
"We recognise the importance of maintaining the principle of freedom of navigation and our opposition to any tolling proposition, she said referring to Iran's plan to demand fees for transiting the Strait. We are working together to strengthen cooperation against scam centres, particularly in Southeast Asia," Wong said.
The Australian foreign minister also said the Quad will coordinate on maritime surveillance efforts initially in the Indian Ocean.
