Given the timing of the change in tone, it seems more likely that what’s making the difference is a realization on both sides that there’s another way this trade war could end – and that possible ending is one the U.S. is very unlikely to lose.

That alternate ending is summed up in one word: decoupling.

The decoupling push is quite different than any U.S. efforts to get China to open up more of its economy to American companies. Instead, it focuses on reducing America’s extremely heavy reliance on China for so much of its manufacturing needs.

Even if China’s economy weren’t so closed off to so many American goods and services, a strong argument has long been made that the U.S. needs to diversify its sources for imports. While finding those new sources wouldn’t necessarily do anything to dent America’s trade imbalances, it would reduce the risks of a major disruption to the U.S. economy based on disputes or other problems connected to a single foreign country.
