Well doing business with China to develop "mutual interest" is not decreasing risk of war with China either. It just makes China stronger while making the West weaker at the same time while making the risk of war even bigger because China has less to fear. There is no such thing as "mutual interest" or "mutual benefits" when doing business with China. It's either all to the benefits or interest of China or nothing. So decoupling or coupling doesn't really make much difference. Decoupling just allows the West to recoup some of the losses and balance the scale a bit better.
China is currently our largest goods trading partner with $559.2 billion in total (two way) goods trade during 2020. Goods exports totaled $124.5 billion; goods imports totaled $434.7 billion. The U.S. goods trade deficit with China was $310.3 billion in 2020.https://ustr.gov › countries-regions
It's absurd to say it's either all to the benefits or interest of China or nothing. Yes, we have a trade deficit with China, but it is our largest export market, after Canada and Mexico.
