On August 18, Russian Foreign Ministry spokeswoman Maria Zakharova affirmed that Moscow resolutely rejected any scenarios related to the presence of NATO member states' troops in Ukraine.
Zakharova warned that the move would lead to an uncontrollable escalation of the conflict with unpredictable consequences.
Russia's response comes as a major European ally of Kiev said it was ready to play a key role in ensuring security for Ukraine after the conflict ended in a so-called "voluntary alliance".
Last weekend, even NATO affirmed that it would deploy a voluntary alliance to Ukraine if necessary.
Also on August 18, speaking after a meeting with US President Donald Trump and European leaders, Ukrainian President Volodymyr Zelensky said that security guarantees for Kiev could be completed in about the next 10 days.
Mr. Zelensky said that Ukraine's partners are working to resolve security concerns, while revealing that "more and more details are appearing day by day".
All of these will somehow be documented within the next 1 to 2 weeks, the Ukrainian leader said.

The revival of plans to send troops to Ukraine, which were once deadly due to force limitations, shows that Europe is not hesitant to face serious consequences, in many cases even having to pay high prices as Russia has warned.
The initiative, initiated by the UK and France in early March with a plan to mobilize about 10,000 soldiers each country, immediately faced strong opposition from senior Russian officials.
Russian Security Council Vice Chairman Dmitry Medvedev warned that the deployment of peacekeeping forces in Ukraine by NATO member states would lead to a full-scale war, specifically the war between NATO and Russia.
Meanwhile, Russian Foreign Minister Sergei Lavrov affirmed that the NATO military deployment plan to Ukraine, although under the name of "peacekeeping forces", still means "official and public" direct participation in the conflict with Russia.
For his part, Kremlin spokesman Dmitry Peskov said the move would be completely unacceptable to us, given the consequences for Russias national security.
