“Concerned about the US statement to withdraw from the Open Skies Treaty. It’s sad if this really happens: I hope the USA changes their minds, ”he said.

Greminger also called the document “one of the pillars of security,” which is necessary to maintain peace and stability in Europe. 

According to him, the US withdrawal from the agreement “will undermine security”.

On May 21, US President Donald Trump announced that the United States would withdraw from the Open Skies Treaty. The decision takes effect after six months.

Deputy Foreign Minister of Russia Alexander Grushko said that Moscow intends to fully use all the rights and fulfill the obligations of the agreement while it is in effect.
