CNN)US Treasury Secretary Janet Yellen on Wednesday criticized the Trump administration's tariffs on China and voiced support for lifting some of the levies, in part to ease very high inflation pressuring the US economy. "Some of the tariffs that were imposed by President Trump in retaliation for China's unfair trade practices, some of them, to me, seem as though they imposed more harm on consumers and businesses," Yellen said during a press conference in Germany ahead of a G7 summit with finance ministers.
