KYIV, Ukraine (AP) — Ukrainian President Volodymyr Zelenskyy on Saturday dismissed the planned summit between U.S. President Donald Trump and Russian President Vladimir Putin, warning that any peace deal excluding Kyiv would lead to “dead solutions.”

The Trump-Putin meeting, scheduled for Friday in Alaska, is seen as a potential breakthrough in the more than three-year war.

Trump had previously agreed to meet with Putin even if the Russian leader would not meet with Zelenskyy, stoking fears Ukraine could be sidelined in efforts to stop Europe’s biggest conflict since World War II.

In a statement posted to Telegram, Zelenskyy said Ukraine’s territorial integrity, enshrined in the constitution, must be nonnegotiable, and emphasized that lasting peace must include Ukraine’s voice at the table.
