The US has demanded control of a crucial pipeline in Ukraine used to send Russian gas to Europe, according to reports, in a move described as a colonial shakedown.

US and Ukrainian officials met on Friday to discuss White House proposals for a minerals deal. Donald Trump wants Kyiv to hand over its natural resources as “payback” in return for weapons delivered by the previous Biden administration.

Talks have become increasingly acrimonious, Reuters said. The latest US draft is more “maximalist” than the original version from February, which proposed giving Washington $500bn worth of rare metals, as well as oil and gas.

Citing a source close to the talks, the news agency said the most recent document includes a demand that the US government’s International Development Finance Corporation take control of the natural gas pipeline.
