A draft deal between the United States and Ukraine over rare earth minerals and other natural resources is “not the one President Zelensky would accept,” according to a source familiar with the negotiations.

The White House and Ukraine have made significant progress toward reaching an agreement that would provide the U.S. with access to Ukraine’s rare earth minerals and tighten the long-term relationship

The progress in talks comes after President Donald Trump and Ukraine President Volodymyr Zelenskyy traded sharp rhetoric about their differences over the matter.

President Trump on Friday said his administration is close to finalizing a deal with Ukraine to access its natural resources as its war with Russia continues.
