“Out of a total of 38 observation flights over Russia planned for 2020, the United States announced 21 flights. In 2017 and 2018, the States conducted 16 observation flights over us, ”Ryzhkov said.

He noted that "in this way, it is obvious that the US military is interested in the Don (Open Skies Treaty. - RT )."

In early October, CNN, citing a source, announced plans for the administration of US President Donald Trump to soon announce a decision to withdraw from the agreement.

The Russian Foreign Ministry noted that the United States did not notify Moscow of its withdrawal from the Don.

The Pentagon later reported that the U.S. Air Force is continuing its aircraft modernization program for use within the Don.
