“Any US decision to withdraw from any binding agreements is a blow to international security,” RIA Novosti quotes Ermakova.
The diplomat said that the statement by the American side about a possible withdrawal from the treaty came as a surprise to Russia.
He also said that Russia will take retaliatory measures if the United States nevertheless withdraws from the treaty, stating that "everything is ready for us."
It is noted that the Open Skies Treaty has been in force since 2002 and allows participating countries to openly collect information about each other's armed forces and activities.
On November 6, Russian Foreign Minister Sergei Lavrov announced that the United States was trying to promote a split throughout the Orthodox world.
