<h1>US seeks to revise penalties on foreign oil buyer after 50% tariffs, urges broader European sanctions amid tensions</h1> A senior US official stated the administration seeks to revise measures imposed on a foreign buyer for purchasing Russian oil and urged broader European sanctions. The US has imposed an additional 25% tariff on that buyer's imports, bringing total US levies to 50%, described as a penalty tied to energy purchases from Russia; further sanctions remain under consideration by the US President. The official also claimed US diplomatic intervention resolved a recent cross-border conflict, while the buyer asserts its de-escalation resulted from direct military-level talks. Recent high-level bilateral meetings occurred amid trade and tariff tensions.
