Ushakov said the discussion on extremely serious issues took place in a working-format setting and informally over dinner, Xinhua reported.

Putin reaffirmed Russia's readiness to continue joint work with the United States in search of political and diplomatic solutions to the Ukrainian issues.

Ushakov said that the Russian side provided clear and comprehensive assessments of the situation unfolding amid the "special military operation".

"In particular, note was taken of the real advances made by the Russian army within the combat zone; confidence was expressed in achieving the stated objectives, and the need to eliminate all root causes of the conflict was emphasized," he noted.

The talks were not confined to an exchange of views on resolving the Ukraine crisis. Economic matters and potential large-scale, mutually beneficial Russian-US projects were also discussed in considerable detail, said Ushakov.

Overall, the negotiations can be described as timely and highly beneficial for both sides. It was confirmed that the heads of state of the two countries will maintain personal contact going forward, and that work through Witkoff and Kushner will continue.

The conversation lasted three hours and 10 minutes.

Ushakov said that the US envoys pledged that during their upcoming contacts in Kiev tomorrow, they would relay observations and assessments they had received directly from the Russian president regarding reaching a durable peaceful settlement to the Ukraine conflict.

On Saturday, Kremlin spokesperson Dmitry Peskov said Putin has ordered a three-day halt to strikes against Kiev, a move linked to preparations for the talks with Witkoff and Kushner.

Witkoff and Kushner landed at Moscow's Vnukovo Airport at 12:52 pm local time (0952 GMT) on Saturday. They were welcomed at the airport by Russia's special presidential envoy Kirill Dmitriev.

Peskov's statement came hours after Ukrainian President Volodymyr Zelensky said that Russia had struck airports in Kiev and its southeastern suburb of Boryspil overnight.

Zelensky also announced separately said that Ukraine is ready to observe a ceasefire in airstrikes against the Russian cities involved in the negotiation process.

"From now through the end of Saturday, as well as on Sunday and Monday, Ukraine is ready to refrain from strikes on Moscow," Zelensky said on X after a phone conversation with Witkoff and Kushner.
