U.S. President Donald Trump said Russia has “lost control” of its diesel oil industry as a result of the war in Ukraine, according to CNBC. The remarks came as the president signaled he is pushing Kyiv toward an energy truce.

Trump’s characterization of Russia’s diesel oil industry frames the conflict’s impact on Moscow’s energy sector, a key pillar of the Russian economy. CNBC reported that the president made the comment while pressing Ukraine to agree to a truce focused on energy.

The push for an energy truce suggests an effort to limit strikes or disruptions affecting energy infrastructure, though the specific terms being sought were not detailed in the report. The reporting focuses on Trump’s stated position that the war has damaged Russia’s ability to manage its oil output.

According to CNBC, the president directed his pressure at Kyiv, indicating that Ukraine is being asked to sign on to the proposed arrangement. The outlet did not report Ukraine’s response to the proposal.

Diesel and other refined oil products remain central to Russia’s export earnings, and any claim about lost control over that industry carries implications for global energy markets. The CNBC report attributed the assessment directly to Trump.

No further details on the timing, scope, or mechanics of the proposed energy truce were provided in the source reporting.
