The question of succession in Kazakhstan has drawn greater attention as the country's long-serving leader Nursultan Nazarbayev advances in age. Nazarbayev has been in power for more than 20 years, and at 72 years old he is well past the average life expectancy for Kazakh males. Kazakhstan is important because of its strategic location -- flanked by Russia to the north and west and by China to the east -- and its sizeable energy and mineral resources. This gives the succession issue significant domestic and regional importance.
