"Preparations for airspace observation are underway. We currently cannot provide more detailed information. The possible measures include airspace surveillance, deployment of combat helicopters and ground-based air defense systems, and restrictions on the airspace use for civil aviation," spokesman Lorenz Frischknecht said.
In late May, Moscow and Washington confirmed that Presidents Vladimir Putin and Joe Biden will meet for a summit in Geneva on 16 June. According to the White House statement, the two presidents will focus on the most important issues concerning bilateral relations.
US President Biden proposed a meeting with his Russian counterpart during a phone conversation on 13 April. The two presidents talked by phone for the first time on 26 January, shortly after Biden’s inauguration. They reached an agreement on the New START Treaty at that time, signing extensions in February. Now set to expire on 5 February 2026, the New START is currently the only arms control agreement between the two countries.
