Kazakhstan's President Nursultan Nazarbayev said Saturday that “a historic decision” will be made at this year's summit;

"During the last 20 years we have been holding talks, rather difficult ones, to agree our approaches, to solve all the issues regarding our cooperation at the Caspian Sea… I believe all issues have been agreed, we are expecting a historic decision to be made tomorrow," Sputnik quoted Nazarbayev as saying.

According to him, the talks focused on ship routes, resources, environment and trade.
