Estonian Prime Minister Taavi Roivas has called for a long-term stationing of NATO troops in his country.
"I consider it very important that we reach a decision at the NATO summit in Warsaw in the summer to maintain the allied presence in Estonia and neighbouring countries," Roivas wrote in an opinion piece published Tuesday in the Postimees daily.
It is also important to have units of European troops alongside US troops, he wrote, adding that Estonia would invest in training camps and barracks for this purpose.
Saying that Estonian security was his highest priority, Roivas wrote that Estonia would also increase its own self-defence capabilities.
Estonia, a former Soviet republic bordering Russia, plans to spend 2.07 per cent of its gross domestic product on defence.
The country has been wary of Moscow's intentions since the start of the crisis in Ukraine, which pits pro-Russian rebels backed by Moscow against the pro-European Kiev government.
