A senior Ukrainian official said two days of talks in Jeddah had strengthened support for Kyiv.

"We had very productive consultations on the key principles on which a just and lasting peace should be built," Ukrainian President Volodymyr Zelenskyy's head of staff Andriy Yermak said in a statement.

Ukraine and its allies have said the talks are an attempt to secure broad international support for Zelenskyy's peace formula, which includes the withdrawal of Russian troops from all of Ukraine, an international tribunal to prosecute Russian war crimes and international security guarantees for Ukraine.

Yermak said different viewpoints emerged, calling the talks "an extremely honest, open conversation."

He added that all the countries present had demonstrated a commitment to the principles of international law and respect for the sovereignty and inviolability of the territorial integrity of states.

Russia, which was not invited, called the meeting a doomed attempt to swing the Global South behind Kyiv.

More than 40 countries, including China, India, the United States, and European countries are taking part in the talks. They are expected to end on Sunday without any written concluding statement.
