U.S.-China relations appear to be entering a more unstable phase, even as both sides signal that they want to keep talks alive. At a summit in Beijing in May, U.S. President Donald Trump and Chinese President Xi Jinping appeared serious about improving trade ties and handling the sensitive Taiwan issue without a wider rupture.

But the broader picture is less reassuring. The article argues that the people and institutions meant to preserve steady diplomacy have been weakened, leaving the relationship more exposed to sudden swings. That erosion makes it harder for Washington and Beijing to manage disagreements before they become larger crises.

Trade and Taiwan remain at the center of the strain. Efforts to rebuild economic cooperation may offer a temporary opening, yet those discussions sit alongside one of the most delicate security questions in the relationship. When diplomatic guardrails are weaker, even areas of apparent progress can be overshadowed by mistrust and miscalculation.

The result is a relationship defined by both engagement and instability. While Trump and Xi may still seek practical cooperation, the decline of diplomatic safeguards means U.S.-China ties are increasingly vulnerable to conflict, policy shocks, and rapid deterioration.
