US President Donald Trump extended for one year the effects of sanctions imposed on Russia due to the annexation of Crimea and the recognition of the independence of self-proclaimed DPR and LPR. This is stated in the materials of the US Federal Register ( .pdf ), presented on February 27.
Trump extended sanctions imposed in 2014, 2018 and 2022 by various US presidents. The document says that all restrictions "must remain in force after March 6, 2025."
“The actions and politics, which are discussed in these decrees, continue to pose an extraordinary and extreme threat to the interests of national security and the foreign staff of the United States,” the document says.
