The US might be trying to isolate Iran internationally, but that hasn't stopped Armenia from deepening its ties with its neighbor to the south, says an article published in the Washington Post, titled "Iran and Armenia strengthen ties". As noted in the article, during a visit to Armenia, Iranian President Mohammad Khatami said that Tehran-Yerevan cooperation will promote mutual interest, regional security and stability. At a meeting with Armenian Defense Minister Serge Sargsian Khatami stressed that Iran supports Armenia, believing that mutual cooperation can help development and security in the Caucasus. In his turn Serge Sargsian voiced his hopes for further expansion of bilateral relations, commenting that cooperation in the fields of culture, education and economy is in the interest of regional security. Besides, Sargsian noted that the linking of the railways of the two neighboring countries would be effective in establishing the north-south corridor.
