Biden's new tariffs show he's willing to play hardball as China ramps up exports, Nobel economist Paul Krugman says

• The tariffs signal that the US won't accept another wave of Chinese imports, Paul Krugman wrote.
• The previous "China shock" was damaging to US employment, given the localized nature of US industry.
• China is relying on heavy production to manufacture its way out of an economic slump.

President Joe Biden's fresh set of China tariffs are a signal that the US will not absorb another flood of Chinese products, Paul Krugman, a top economist, wrote in an op-ed for The New York Times.
