Why did Washington impose sanctions on China before the Trump-Xi summit?

New U.S. sanctions against Chinese companies just before Donald Trump’s visit to Beijing highlight the growing tendency to use economic pressure as a primary instrument of American diplomacy.

The timing tells the story. On May 8, the US Treasury announced sanctions on 10 individuals and companies — several based in China and Hong Kong — accused of facilitating Iran’s acquisition of materials used in Shahed drones and ballistic missile programmes. According to the Treasury Department, some firms allegedly supplied insulation materials and procurement services linked to Iran’s military-industrial network. Reuters reported that the sanctions came just days before Trump’s scheduled meeting with Chinese President Xi Jinping in Beijing.

He wants to completely dodge the impression that the US has lost in Iran.

Whether on tariffs, NATO burden-sharing, or Iran, Trump has frequently relied on pressure tactics to create bargaining leverage before high-level meetings. The assumption is that economic coercion raises the costs of resistance and therefore increases the incentives for compromise. But this strategy works only if the other side believes accommodation is less costly than defiance. That assumption is becoming increasingly questionable in the case of........
