In a statement, the White House said Trump highlighted to his fellow world leaders at the G-20 summit that the US had "marshaled every resource at its disposal to respond to the crisis".
King Salman urged leaders to expand efforts to provide access to vaccines and treatments, as well as buoy the economies of developing nations wracked by the economic impacts of COVID-19.
But their declaration also painted a sober picture of the continuing health and economic crisis.
"While containing the virus, we need to restore the secure and smooth operation of global industrial and supply chains".
"We must continue to work together to ensure that no one is left behind, as the world recovers from this crisis".
The prime minister also "advocated for the equitable access to vaccines, therapeutics and diagnostics, because we can't end the pandemic in Canada without ending it everywhere". "And we can not forget that strong national health systems are necessary for effective vaccine distribution". China and Russian Federation have already begun administering their own vaccines despite questions about whether they faced sufficient safety checks.
Despite the pledges, however, experts say the summit represented a missed opportunity for addressing the biggest issues facing the world today - in part because most of the commitments are not new.
"There [are] obviously shortages but there is clear commitment ... toensure equitable distribution of vaccine to every country", Al-Jadaan said.
Moreover, in a recent statement by US National Security Advisor, Robert O'Brien, he expressed his hope that Saudi and Bahraini air space would open for Qatar Airways flights within "70 days". So we can not resolve this issue in certain parts of the world because the rest of the world will suffer.
G20 leaders said that while global economic activity has partially picked up thanks the gradual reopening of some economies, the recovery is uneven, highly uncertain and subject to downside risks.
"The G20, which has spent, as they proudly declare, $15 trillion to counter COVID just this year, couldn't even agree to write down that they would come up with $4.5 billion to get those vaccines delivered around the world", Kirton said. "This is why I called G20 Leaders to commit to fund $4.5 billion".
In their communique, the leaders reiterated their annual commitment to supporting global trade and restated their resolve to fight climate change.
US President Donald Trump made a brief appearance at the opening session, lauding his administration's achievements on coronavirus before logging off and going golfing, while other leaders braved technical quirks and the lack of opportunity for spontaneous interactions.
"We continue to be willing to engage with our Qatari brothers, and we hope that they are as committed to that engagement", said bin Farhan in October during a virtual event hosted by the Washington Institute for Near East Policy, a USA based think-tank.
However, the final communique did not spell out how the massive cost of the exercise would be underwritten.
Saudi Arabia spent years planning for this summit - the first such time the oil-rich Middle Eastern country was on tap to host a G20 meeting - only to see its planned lavish celebrations upended by the pandemic and travel restrictions. "Italy is ready", Conte said.
"We are aware of the scope of our responsibility but also of the difficulty of our task", he said, adding: "The health and socio-economic answer to the pandemic, which has caused and continues to cause enormous suffering tomankind and has already struck significant blows to the global economy, will obviously continue to be at the top of our agenda, to keep high the commitment of the worldwide community in the reaction to COVID-19".
