The announcement, on April 2, 2025, of “reciprocal tariffs” by the United States has opened a sequence of profound break with decades of established trade policy practices, where the administration behaviour has been marked by dogmatic blindness, amateurism, and self-serving interests. 

A data-based analysis shows that widespread geoeconomic fragmentation of world trade is not visible, at least so far. In contrast, the geopolitically-motivated challenges to international coordination are striking, notably in relation with China's surging surplus in manufactured goods trade.

The link between financial self-reliance and geopolitical power has long been debated. The unbalanced Sino-American trade relationship has created asymmetric financial ties which generate potential sources of leverage for both parties and will not quickly disappear. Absent a clarifying major crisis, it will be difficult to definitively determine which party has greater leverage.
