Leaders of the Group of 20 major economies pledged Monday to do their utmost to ensure all nations have fair access to COVID-19 vaccines when they are developed and to cushion the global economy from the impact of the coronavirus pandemic.

The G-20 countries will "spare no effort" to ensure "affordable and equitable access" to COVID-19 therapeutics and vaccines for everyone, the leaders said in a declaration released after their two-day virtual meeting chaired by Saudi Arabia.

The leaders said they "stand united in our conviction that coordinated global action, solidarity, and multilateral cooperation are more necessary today than ever to overcome the current challenges."

While the world economy is partially picking up, its recovery from the slump caused by the novel coronavirus pandemic remains "uneven, highly uncertain and subject to elevated downside risks," the G-20 leaders said, touching on renewed outbreaks in some economies.

"We underscore the urgent need to bring the spread of the virus under control, which is key to supporting global economic recovery. We are determined to continue to use all available policy tools as long as required to safeguard people's lives, jobs and incomes," the leaders said.

During the summit, Japanese Prime Minister Yoshihide Suga emphasized the importance of guaranteeing universal access by supplying treatment drugs and vaccines for COVID-19, the disease caused by the coronavirus, through a system to manage global patents, according to a senior official.

An international framework to manage patents "would contribute to a large supply of COVID-19 drugs at an affordable cost for all countries and G-20 support is vital," Suga was quoted as saying by the official.

He also reiterated his commitment to make Japan carbon neutral by 2050, as he pledged in his first policy speech in parliament last month, according to the official.

"We need to adjust our mindset to a paradigm shift in which proactive climate change measures bring about the transformation of industrial structures as well as our economy and society, leading to dynamic economic growth," the official quoted Suga as saying.

Suga also spoke about marine plastic pollution, which Japan aims to reduce to zero on a net basis by 2050, as well as the country's push for female empowerment, according to the official.

As for the Tokyo Olympics and Paralympics, which have been postponed to next summer from this year due to the pandemic, the G-20 hailed in their declaration Japan's determination to host the events.

The G-20 nations, meanwhile, endorsed a plan, already agreed by their finance ministers and central bank governors, to extend their debt repayment suspension program for poor countries by six months to June 2021. Their finance chiefs will examine by next spring whether to extend the program by another six months.

The debt relief program, called the Debt Service Suspension Initiative, was launched in May by the G-20 and Paris Club of traditional creditor nations after the outbreak of the virus saw vulnerable countries saddled with higher financing costs.

While the G-20 declaration showed support for multilateral trading systems, there was no mention of fighting protectionism.

The G-20 leaders have not used the word protectionism in their statements since 2018 after opposition from the United States, which has implemented protectionist trade measures under outgoing President Donald Trump's "America First" policy.

Trump briefed his counterparts on the "economic model he has enacted" such as through cutting regulations and negotiating trade agreements grounded in the principles of "fairness and reciprocity," while encouraging the G-20 to continue to work together to achieve prosperity and peace for all nations, according to the White House.

The second virtual G-20 summit under Saudi Arabia's presidency, following the first in March, came as many countries in Europe and elsewhere have been seeing spikes in virus cases as winter approaches, increasing downside risks to growth recovery and uncertainty over the coming months.

The pandemic has led to strict travel restrictions and hard lockdowns in many cities across the world that have left major economies reeling from annualized contractions of a real 20 to 50 percent in the April-June period from the previous quarter. They sharply recovered in the July-September period but were still behind pre-pandemic levels.

The G-20 groups Argentina, Australia, Brazil, Britain, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, the United States and the European Union.

Saudi Arabia handed over the rotating G-20 presidency to Italy.

The following is the gist of a joint declaration released Monday after a two-day virtual meeting by leaders of the Group of 20 major economies.

The G-20:

-- stands united in conviction that multilateral cooperation is more necessary today than ever.

-- will continue to spare no effort to put economies back on a path to restoring growth.

-- sees global economic recovery as uneven, highly uncertain and subject to downside risks and is determined to continue to use all available policy tools to support the recovery.

-- will spare no effort to ensure affordable and equitable access to effective COVID-19 diagnostics, therapeutics and vaccines for all people.

-- is committed to implementing debt repayment suspension program for poor nations.

-- commends Japan's determination to host Tokyo Olympics and Paralympics next summer.
