Iranian media reported today that Iran and Tajikistan signed a memorandum on defence cooperation. Iranian Defence Minister Ali Shamkhani and Tajik Defence Minister Sherali Khairulloyev signed the memorandum in Tehran. Part of the agreement is for Iran to help train Tajikistan's border guards, who are in the process of taking over duties along the Tajik-Afghan border from Russian border guards. Russia's border guards have been monitoring the Tajik-Afghan border since Tajikistan became independent in late 1991. According the state news agency IRNA, Tajik military personnel will receive instruction and training in Iran. Shamkhani said that agreement is part of the Iranian government's efforts to build regional trust in Central Asia and the Caucasus and resist the threat of further foreign Intervention in the area. Khairulloyev is on a five-day visit to Iran.
