There has been much hype about the signing of Phase One (and probably only) US-China trade deal. However based on a front page story in today's Washington Post, there is not much there. The US did not raise tariffs as planned, but tariff still remain on two thirds of the sectors that had them, although some were halved. But numerous US sectors see no change at all and are now viewing the situation as not likely to improve, with them suffering losses of business likely to return. Among those are chemicals, apparel retailers, and auto parts. In these and other sectors there is not much reduction of uncertainty regarding US-China trade, so not likely much increase in investment.
The main items in it besides no worsening of tariffs, China has made promises not to pressure US firms to turn over technology and also to increase imports from the US by $200 billion over the next two years, especially in energy and agriculture. So maybe US soybean farmers will no longer need the bailouts of billions of $ Trump has been providing to them. However, such promises have been made in the past.
As it is, I am watching commentators on Bloomberg, and about the most any of them are willing to say is that this "puts a floor" on the "deterioration" of US-China trade relations. That is far from some dramatic breakthrough, and most of the tariffs put on as part of the US-China trade war remain in place.
