LONDON: Russian officials have no desire to halt Russia’s almost 4-year-old invasion of neighboring Ukraine and think they can “outsmart” the United States during talks with Washington about how to end the war, a senior European intelligence official told The Associated Press.

Kaupo Rosin, the head of Estonia’s foreign intelligence service, said Moscow is playing for time in the talks with Washington and “there is absolutely no discussion about how to really cooperate with the US in a meaningful way.”

Rosin, who spoke at an online briefing with reporters ahead of the publication of Estonia’s annual security report on Tuesday, said the findings were based on intelligence his country gathered from “Russian internal discussions.” He did not elaborate on how the information was obtained.

Russian officials have publicly insisted they want a negotiated deal, but they show little willingness to compromise and remain adamant their demands must be met.

US-brokered talks between envoys from Russia and Ukraine in recent weeks have been described by officials from both sides as constructive and positive, but there has been no sign of any progress on key issues in the discussions.
