<h1>Senior U.S. commerce official criticizes Country A for restricting imports from Country B while exporting, warns of retaliation</h1> A senior U.S. commerce official criticized Country A for restricting imports from Country B while exporting to Country B, arguing Country A refuses to buy even small amounts of agricultural product X and imposes tariffs that disadvantage Country B. The official said Country B will seek 'fair and reciprocal' treatment, threatening retaliatory tariffs until trade imbalances are corrected and warning firms that noncompliance will make business difficult. Country B has already imposed about 50% tariffs on Country A, including a 25% levy tied to purchases from a third country; Country A labeled the measures unfair and defended its energy-buying decisions as driven by national interest.
