Israeli Foreign Minister Eli Cohen confirmed Tel Aviv's support for Ukraine in its difficult times, after his arrival in the capital, Kiev.
In the first visit of its kind since the outbreak of the war.
Cohen - who was invited to Kiev by his Ukrainian counterpart Dmytro Kuleba - announced that his government would reopen the Israeli embassy in Kiev.
Israel's Foreign Ministry said Cohen was scheduled to attend the reopening of the embassy in Kiev, which has returned to full activity.
Israel had condemned the Russian war in Ukraine, but its assistance to Kiev was limited to humanitarian aid and protective equipment.
Meeting with Zelensky
According to the Israeli newspaper "Haaretz", Cohen is expected to meet Ukrainian President Volodymyr Zelensky in a meeting "Kiev was keen to confirm that it is conditional on obtaining certain concessions from Israel."
The newspaper quoted a senior Ukrainian official - who did not reveal his identity - that the meeting with Zelensky would not take place if Cohen came to Ukraine "empty-handed";
That is, without agreeing to at least some of the requests that Ukraine made to Israel.
These requests include - according to the newspaper - economic aid in the form of a loan worth half a billion dollars, and military support.
Kiev also stipulated that Israel support the upcoming UN vote on Zelensky's peace initiative, which includes a demand for a complete Russian withdrawal from "all occupied Ukrainian territories" since 2014.
Israeli Prime Minister Benjamin Netanyahu - who returned to power last December - previously spoke of reviewing Israeli policy on the Ukrainian-Russian war, but he did not pledge to provide any weapons to Kiev.
