At a moment when the world's great trading relationships are under strain, China's top diplomat has extended an unusual public appeal to Europe: step back from the edge of a trade war before the costs become irreversible.

It is a rare moment of diplomatic candor — though whether it signals genuine concession or strategic positioning remains the central question for both blocs.
