KIEV (Reuters) - Ukrainian President Petro Poroshenko will meet U.S. President Donald Trump in Washington on Tuesday for talks on security, political and economic issues, Poroshenko's office said.

"It is very important that my meeting, as the Ukrainian president, in the White House will be earlier than (Russian President Vladimir) Putin's meeting," it quoted Poroshenko, who is already in the United States, as saying.
