President Moon also met on Saturday with the CEO of AstraZeneca, Pascal Soriot, and asked for his continued cooperation with South Korea for the stable production and supply of COVID-19 vaccines.
They spoke on the sidelines of the summit.
Here's President Moon.
"South Korea will cooperate actively to address the global vaccine shortage. I ask AstraZeneca to use South Korea's production capacity to ensure a steady supply of vaccines globally."
The South Korean bio company SK Bioscience produces the AstraZeneca vaccine under a consignment contract.
In their 22 minute conversation, Moon said that vaccine production has become an important step for South Korea in becoming a global vaccine hub, calling for continued collaboration so that vaccinations can be done smoothly in the second half of the year.
The AstraZeneca chief was quoted as saying that South Korea is the "top priority" partner and expressed hope of maintaining his company's partnership with SK Bioscience due to the Korean company's top notch vaccine quality control.
The AZ vaccine was the first to be administered in South Korea when the country's vaccine campaign started in February, and is so far the most widely administered as well.
