To discuss win or loss, you have to consider the objective of Trump. Trump's objective is to move the jobs from China to US by punishing the business which outsourced production to China. What will happen is up to guess, but my guess is that the business will move the production to other countries, which however will take a lots of time since the supply chain is complicated.
So in the end, it is likely US will not get the jobs Trump promised and its business and consumers pay the higher tariff for several years, and China will loss the some of the jobs to other countries. Neither country wins.
