National security adviser says Ukraine is wrong to push back against Trump’s approach to peace talks with Russia

White House officials have told Ukraine to stop badmouthing Donald Trump and to sign a deal handing over half of the country’s mineral wealth to the US, saying a failure to do so would be unacceptable.

The US national security adviser, Mike Waltz, told Fox News that Ukraine’s president, Volodymyr Zelenskyy, should “tone down” his criticism of the US and take a “hard look” at the deal. It proposes giving Washington $500bn worth of natural resources, including oil and gas.
