German Finance Minister Olaf Scholz on Tuesday welcomed Washington's backing for a global minimum corporate tax, calling it a "great step forward" in the battle to stem the erosion of government revenues. "The support of the USA gives this initiative a strong tailwind," Scholz told reporters, a day after US Treasury Secretary Janet Yellen said the US was pushing G20 countries to create "a more level playing field" in the taxation of multinational companies. mfp/dlc/lth
