Russian President Vladimir Putin and his US counterpart Donald Trump are meeting at a military base in Alaska.
Going into it Mr Trump had reportedly told European leaders that his goal for the summit was to obtain a ceasefire between Moscow and Kyiv.
The President says he "won't be happy" if a ceasefire isn't agreed during his talks.
Ukraine is not invited to the talks, but Vlodomyr Zelensky says his country is counting on America. It's now three and a half years since Russia launched a full-scale invasion of Ukraine.
