- Well, four days of top level economic meetings between the US and China coming to a close today. Janet Yellen's second trip to China in nine months, the Treasury Secretary saying that there is, quote, "much more work to do in terms of diplomacy between the two nations." Secretary Yellen spoke at a press conference earlier today, recapping some of her conversations with Chinese leaders, specifically calling out concerns around China's economic strategies and the negative spillovers on the US and the globe, including the country's desire to expand manufacturing in EVs, lithium ion batteries, and solar.
