There are few issues on which the dominant consensus in Washington has changed as rapidly in recent years as it has on China. Donald Trump made taking on China a core pillar of his campaign and presidency. And while Joe Biden has toned down the harsh anti-China rhetoric of his predecessor, many of his administration’s policies have gone even further than Trump’s did.In October the Biden administration unveiled sweeping controls on advanced chip exports to China — a move that former Trump officials have described as a sharp break from where their administration’s policies were. And the Biden administration doesn’t intend on stopping there: It plans to roll out further controls that target China’s biotech and clean energy sectors.Meanwhile, Biden has repeatedly voiced such strong declarations of American military support for Taiwan that his own administration has had to walk them back. And, in Congress, China policy is one of the few areas Democrats and Republicans seem willing to work together — almost always in the direction of getting tougher on Beijing.Jessica Chen Weiss is a political scientist and China scholar at Cornell. From August 2021 to last July, she was a senior adviser in the Biden State Department. And she emerged from that experience as one of the most outspoken critics of Washington’s more hawkish turn regarding China. “The more combative approach, on both sides, has produced a mirroring dynamic,” Weiss wrote in a 2022 essay called “The China Trap.” She worries that Beijing and Washington are misreading each other’s ambitions, resulting in a “downward spiral” of mutual aggression that will leave both sides — and the world more broadly — less prosperous and secure.So I asked Weiss to come on the show to help me understand the state of U.S.-China relations and why she thinks it’s headed in the wrong direction.Mentioned:“The China Trap” by Jessica Chen Weiss“A World Safe for Autocracy?” by Jessica Chen WeissBook Recommendations:Seeking Truth and Hiding Facts by Jeremy L.
