The defense cooperation between the US and Azerbaijan does not threaten the neighbor states, US Ambassador to Azerbaijan Rino Harnish stated. He also refuted reports on quartering the US troops in Azerbaijan for guarding the Baku-Tbilisi-Ceyhan oil pipeline. In his words the US-Azerbaijan military cooperation covers two fields: bringing the Azeri army to conformity with the international standards and the minimization of threats at the marine and overland borders of the country. In part, the matter concerns prevention of contraband and illegal delivery of weapons of annihilation.
