President Hassan Rouhani has postponed his planned visit to Kyrgyzstan due to his Kyrgyz counterpart's illness, an informed source said. The trip was scheduled for October 4-5, the source said, adding that it will be rescheduled for a few weeks later, Tasnim News Agency reported. Hospitalization of Kyrgyzstan's President Almazbek Atambayev in Russia has been cited as the reason for the postponement of Rouhani's visit. Atambayev went to Russia for medical help last week after falling ill in Turkey days after his 60th birthday. In recent years, Tehran and Bishkek have worked to enhance bilateral ties in different fields. In September 2015, Atambayev paid an official visit to Iran. During the trip, the two sides signed eight memorandums of understanding to promote cooperation in such fields as energy, agriculture, trade and air transport.
