<h1>US says it used aggressive economic leverage, including secondary tariffs, to pressure rival to stop bombing and cut oil revenues</h1> A senior US official said the administration has used 'aggressive economic leverage,' including secondary tariffs on an Asian trading partner, to pressure a rival state to cease bombing a neighboring country and to reduce revenues from its oil sector. The official asserted the measures aim to incentivize political concessions and potential reintegration into the world economy if hostilities stop. The targeted partner rejects the charges, saying its energy purchases reflect national interest and market dynamics, while diplomatic tensions have risen after substantial tariff increases and public exchanges between the governments.
