Global trade is wobbling under the effect of a new escalation between Washington and Beijing. Donald Trump is reigniting the tariff offensive against China, rekindling a trade war that marked his previous term. Beijing, far from backing down, is deploying a firm response, determined to defend its strategic interests. This renewed showdown between the two superpowers resonates well beyond customs, threatens global economic balances, and stirs tensions in international markets. A confrontation whose implications could be felt well beyond American and Chinese borders.
