The widened trade potentially helps both countries. The US would get to export many more products to China and protect jobs at home, while China could revitalize its economy and shake its reputation as a source of cheap labor. Both sides still have to hammer out the final details, and there's a chance that Japan and South Korea will want to have a say. There are also no guarantees that the US will get the growth it wants given that China's tech industry is surging and could overshadow American accomplishments. At the least, the deal should lower the costs of making and shipping the devices you buy. You won't necessarily see prices go down, but you're likely to see both American and Chinese products in more places.
