What happened
Trump eased Russian diesel sanctions and announced an energy ceasefire that neither warring side had confirmed, according to Reuters. [12]
Why
US envoys said the deal could bring Moscow back to negotiations; Trump also argues it will lower American energy prices. [12]

Russia gains export revenue while Ukraine reports continued attacks on energy facilities; the AP says the deal weakens Kyiv’s and its allies’ pressure campaign. [6][7]
The catch
More than 2.25 million barrels would enter US and global markets, but experts say that is less than one day’s supply for the US transport sector alone. [12]

Who pays
Russian strikes caused Ukrainian power outages; Kyiv says the diesel arrangement would also provide resources for Russia's war. [2][10]
The catch
Ukrainian officials reported energy attacks after the announcement, and the published accounts supplied no agreed enforcement terms. [2][12]
