UNITED NATIONS — The U.N. chief says it’s “very frustrating” that leaders of the 20 major industrialized nations didn’t come together in March and establish a coordinated response to grapple with the coronavirus in all countries as he proposed.

The result, he says, is every country is taking its own sometimes contradictory actions, and the virus is moving “from east to west, north to south,” with second waves of infections now affecting many countries.

Ahead of the Group of 20 summit next month, Secretary-General Antonio Guterres said in an interview with The Associated Press that he hopes the international community now understands “they need to be much more coordinated in fighting the virus.”

Guterres says the United Nations also will be “strongly advocating” during the G-20 summit for a guarantee that when a vaccine is available, “it becomes indeed available and affordable for everyone, everywhere.”
