In a surprise to no one. This is just tit for tat in the Trump-Biden trade war with China.
China initiated the "trade war" years before any American politician acknowledged it.
China, and I think somewhat to their credit, learned tons from the stupidity of Russians and were never going to be so thoroughly broken. And it's understandable; that's what we'd do. Nonetheless, China isn't so powerful as to dictate terms.
It seems like China's risk calculation was suffer short term money loss and foreign products and services now, to make own and control the market access and structure later making back the money.
