U.S. Ambassador to Ukraine Marie Yovanovitch noted the absence of changes in American policy on the Crimea issue.

"American policy regarding Crimea is unchanged: we view Crimea as part of Ukraine and there is no change in this policy," the diplomat said during the discussion at "Kyiv Forum Talk in: What One Should Expect from 2018 NATO Summit?" in Kyiv on Tuesday.

Yovanovitch also recalled that the U.S. provides a significant amount of assistance in various issues, in particular, in the sphere of security.
