Trump threatens Zelensky with 'big problems' | 31 March 2025 | U.S. President Donald Trump has warned Vladimir Zelensky to think twice before rejecting the latest version of Washington's proposed minerals deal -- already far harsher than an earlier draft derailed by the Ukrainian leader's outburst at the White House. Trump has repeatedly demanded that Kiev reimburse what he claims are hundreds of billions of dollars in U.S. aid through Ukraine's mineral wealth, originally focusing on "rare earths." A previous version of the deal was supposed to be signed in early March but was abruptly withdrawn after Zelensky clashed publicly with Trump and Vice President J.D. Vance during an Oval Office meeting.
