"Our greatest defence against Covid-19 is solidarity and cooperation", the United Nations chief was speaking at a virtual summit of G20 leaders under the theme "Building an inclusive, sustainable and resilient future", where he highlighted the importance of G20 leadership in the fight against the pandemic and the effort to build back better, Xinhua news agency reported.
The 15th G20 Summit is being hosted by the city of Riyadh, Saudi Arabia, under the country's presidency, from November 21 to 22 this year.
U.N. Secretary General Antonio Guterres on Friday stressed the importance of worldwide access to vaccines against COVID-19, the disease caused by the novel coronavirus, saying it is the only way to stop the pandemic.
"But I want to repeat the call on G20 members to support the ACT-Accelerator and its COVAX facility".
"All of these efforts are vital to save lives and provide an exit strategy out of this global economic and human crisis", said the top United Nations official.
The UN chief noted that the organisation was founded on the principles of dignity and worth of the human person, "without distinctions of race, colour, ethnic or national origin".
The statement said that the upcoming 2020 Afghanistan Conference on November 23-24, co-hosted by Afghanistan, Finland, and the United Nations, is an opportunity to renew commitments to the peaceful development and future prosperity of the country.
He said he will call for the bloc to increase financial resources available to the International Monetary Fund.
To build an inclusive, resilient and sustainable post-COVID world, public spending must be linked with achieving the Sustainable Development Goals, said the Secretary-General.
"The European Union has a crucial role in ensuring that developing countries in need have the necessary support to recover sustainably from COVID-19 and to enhance their own climate ambition - through assistance for mitigation, adaptation and resilience", the secretary-general added.
"The recovery must help to reconcile humankind and nature on all fronts".
