Raising the efficiency of the Armenian border defense proceeds from the interests of the entire international community, U.S. Ambassador John Evans stated during the opening ceremony of a new training center of the Armenian frontier troops. In his words, the U.S. has been for a long time assisting Armenia in exercising control of the state borders. "The whole world should be interested in non-proliferation. For a sovereign state like Armenia the border defense becomes a priority issue and we are glad to render assistance in such an important matter," the U.S. Ambassador to RA said.
