bilateral - adjective

Recently, President Bush and Iraqi Prime Minister Nouri al-Maliki signed a joint communiqué in which the U.S. committed to helping Iraq defend its government against internal and external threats. In response, the Maliki government asked for a one-year renewal of the current United Nation's Security Council Resolution that governs U.S. forces operating in Iraq. Mr. Maliki is also committed to working out bilateral relations with the U.S. to govern future American operations in his country.
