HELSINKI -- Ukrainian President Volodymyr Zelensky said on Wednesday that while Kiev seeks a ceasefire, it will not accept any territorial concessions to Russia.

Zelensky and First Lady Olena Zelenska arrived in Finland on Tuesday afternoon for a one-day official visit, during which he met with Finnish President Alexander Stubb.

At a joint press conference following their meeting on Wednesday, Zelensky emphasized that Ukraine's sovereignty and territorial integrity remain non-negotiable when asked about the "red lines" in potential armistice talks.

He stressed that a ceasefire would eventually be implemented, but Ukraine would not accept Russia's territorial demands.

Zelensky declined to comment on details of a phone call between US President Donald Trump and Russian President Vladimir Putin. He said he would wait until speaking with Trump directly before making a statement.

In a telephone call on Tuesday, Putin and Trump discussed the ongoing conflict in Ukraine and ways to restore bilateral ties.

While not ruling out future negotiations between Ukrainian and Russian delegations, Zelensky insisted that talks could only proceed if Russia halted its attacks. He also reiterated Ukraine's readiness to send a delegation to the United States for ceasefire discussions.

Stubb reiterated Finland's continued support for Ukraine, stressing that "Ukraine must emerge from the war as an independent country."

Stubb underlined that besides the Ukrainian, Russian and US teams, there should also be a European team in the talks.
