Concerns have mounted in Europe and Ukraine that Kyiv may be pressed to give up land or accept other curbs on its sovereignty.

As U.S. President Donald Trump and his Russian counterpart, Vladimir Putin, prepare for a bilateral meeting on Aug. 15 in Alaska, the aims of the U.S., Russia, and Ukraine appear to contradict each other.

Trump and Putin will meet in Alaska on Friday to try to resolve the three-year war but the EU has insisted that Kyiv and European powers should be part of any deal to end the conflict.
