US President Joe Biden would host the first-ever in-person Quad summit on September 24 which will be attended by Prime Minister Narendra Modi, Prime Minister Scott Morrison of Australia and Japanese premier Yoshihide Suga, the White House announced on Monday.

The four leaders would discuss deepening their ties and advancing practical cooperation on areas like combatting COVID-19, addressing the climate crisis and promoting a free and open Indo-Pacific, the White House Press Secretary Jen Psaki said.

In March, President Biden hosted the first-ever summit of the Quad leaders in the virtual format that vowed to strive for an Indo-Pacific region that is free, open, inclusive, anchored by democratic values, and unconstrained by coercion, sending a subtle message to China.

"President Joseph R. Biden, Jr. will host the first-ever Quad Leaders Summit at the White House on September 24. President Biden is looking forward to welcoming to the White House Prime Minister Scott Morrison of Australia, Prime Minister Narendra Modi of India, and Prime Minister Yoshihide Suga of Japan," Psaki said.

Confirming the news, India's Ministry of External Affairs said in a statement, "The Leaders will review progress made since their first virtual Summit on March 12 and discuss regional issues of shared interest."

"As part of their ongoing efforts to contain the COVID-19 pandemic, they will review the Quad Vaccine initiative which was announced in March this year," it added.

PM Modi is also scheduled to address the General Debate at the United Nations General Assembly (UNGA) on September 25 in New York.

The Biden-Harris administration has made elevating the Quad a priority, as seen through the first-ever Quad Leaders-level engagement in March, which was virtual, and now this Summit, which will be in-person, she said.

Hosting the leaders of the Quad demonstrates the Biden-Harris administration's priority of engaging in the Indo-Pacific, including through new multilateral configurations to meet the challenges of the 21st century, she said.

According to the White House, the Quad Leaders will be focused on deepening their ties and advancing practical cooperation on areas such as combatting Covid-19, addressing the climate crisis, partnering on emerging technologies and cyberspace and promoting a free and open Indo-Pacific.

The Quad summit will take place amidst China's aggressive behaviour in the resource-rich South China Sea.

Beijing claims almost all of the 1.3 million square miles South China Sea as its sovereign territory. China has been building military bases on artificial islands in the region also claimed by Brunei, Malaysia, the Philippines, Taiwan and Vietnam.

In November 2017, India, Japan, the US and Australia gave shape to the long-pending proposal of setting up the Quad to develop a new strategy to keep the critical sea routes in the Indo-Pacific free of any influence.
