What is Open Skies treaty ?

The treaty allows 34 countries to conduct unarmed surveillance flights over one another’s territories — including the US and Russia.

It was signed in 1992 and went into effect in 2002.

Kyrgyzstan has signed, but not ratified the treaty.

The treaty “was designed to enhance mutual understanding and confidence by giving all participants, regardless of size, a direct role in gathering information through aerial imaging on military forces and activities of concern to them.”

The U.S. has given notice that it will exit the Open Skies Treaty.
