(AP) — Leaders of the world’s most powerful economies will convene virtually to coordinate a response to the fast-spreading new coronavirus. The virus has shuttered businesses and forced well over a quarter of the world’s population into home isolation. Thursday’s meeting for the Group of 20 nations was being chaired by Saudi Arabia’s King Salman. The kingdom, which is presiding over the G20 this year, says it organized the meeting to advance global efforts to tackle the pandemic and its economic implications. People worldwide are losing their incomes amid closures, curfews and lockdowns, and the meeting comes amid criticism that the world’s wealthiest countries have not taken cohesive action against the virus or its economic impact.
