LONDON — The finance ministers of the most advanced economies, known as the Group of Seven, have backed a U.S. proposal that calls for corporations around the world to pay at least a 15% tax on earnings.

"G-7 finance ministers today, after years of discussions, have reached a historic agreement to reform the global tax system, to make it fit for the global digital age — and crucially to make sure that it's fair so that the right companies pay the right tax in the right places," U.K. Finance Minister Rishi Sunak announced in a video statement on Saturday.
