Russian President Vladimir Putin's talks with US Special Envoy Steve Witkoff, US President Donald Trump’s son-in-law Jared Kushner, and White House Senior Advisor Josh Gruenbaum in Moscow were constructive and extremely frank, Russian presidential aide Yuri Ushakov said, RIA Novosti reports.

"We concluded that without a resolution to the territorial issue, it is impossible to expect a long-term settlement [to the Ukraine issue]. We agreed that the first meeting of the trilateral working group on security issues—with the participation of representatives of Russia, the US, and Ukraine—will take place in Abu Dhabi on Friday," Ushakov noted.

"The Russian security negotiating group has been formed and will leave for the UAE in the coming hours. It includes high-ranking officials from the Ministry of Defense. The Russian delegation that left for Abu Dhabi has received specific instructions from Putin," he added.

The heads of the bilateral economic group, Russian president’s special representative Kirill Dmitriev and US Special Envoy Steve Witkoff, will meet in Abu Dhabi.

According to Ushakov, the Russian party has emphasized its readiness to invest $1 billion from previously frozen Russian assets in the Gaza “Board of Peace,” and the remaining funds from the frozen reserves can be used for territorial reconstruction after the signing of a peace treaty between Russia and Ukraine.

“Russia will continue to consistently pursue the goals of the Gaza ‘Board of Peace’ until a settlement is achieved through political and diplomatic means,” the Russian presidential aide concluded.
