Russia plans to hold trilateral talks with Ukraine in Abu Dhabi in November under US mediation, with the meeting seen as having "decisive significance" for resolving the Ukraine conflict, Kremlin aide Yury Ushakov said on Friday, according to Russia's state-run news agency RIA Novosti.

Moscow and Washington have begun coordinating the date of the talks, but no final decision has been made, Ushakov said, adding that the timing would depend on various domestic and international factors.

Asked about the possible presence of European representatives, Ushakov said they would not take part in the trilateral talks, even if they met with Ukrainian or US officials.

Ushakov previously said the trilateral meeting would take place after November 4.

Ukrainian President Volodymyr Zelenskyy said on Wednesday that he hoped the meeting would take place between November 6 and 10. Kyiv also wanted Europe to be involved in discussions on ending the war, he said.

Military confrontation continues

Preparations for trilateral talks do not imply any commitment to limiting military operations, Kremlin spokesman Dmitry Peskov said on Friday.

"We have repeatedly stated that we are against a ceasefire that would give the Ukrainians a respite," Peskov said.

Russian Foreign Minister Sergei Lavrov also said on Friday that Moscow's position on the Ukraine conflict remained unchanged.

Speaking to reporters on the sidelines of a G20 meeting in Atlanta, Lavrov said fundamental issues in relations between Russia and the United States remained unresolved, citing continued sanctions against Moscow and the supply of weapons to Kyiv.

The US State Department said on Friday it had approved the sale of 500 Patriot Advanced Capability-3 (PAC-3) Missile Segment Enhancement (MSE) missiles and related equipment to Ukraine, valued at $2.1 billion.

The proposed sale also includes classified and unclassified spare parts, as well as logistical and program support, the department said.

The purchase will be financed through contributions from Canada, Germany and Norway under the JUMPSTART program, as well as national funds backed by the European Union's Ukraine Support Loan. No US funds will be used for the purchase, according to the department.

Zelenskyy said on social media that Ukraine had set key priorities for the further use of its long-range strike capabilities and would expand its deep-strike units.

He said every Russian strike on Ukrainian cities and communities would receive what he called "a fully justified response."
