"Ukraine's president notified Vladimir Putin of his plan to settle the situation in Ukraine's southeast," Putin's spokesman Dmitry Peskov told Russian news agencies.
"On top of that, the presidents discussed issues related to the development of bilateral ties," Peskov said.
Poroshenko's office said the two leaders held "substantial and lengthy" talks in which they discussed steps needed to "settle the situation through peaceful means".
Putin and Poroshenko met on the sidelines of the D-Day anniversary ceremonies in Normandy last week, their first meeting since pro-Western Poroshenko was elected to the top post on May 25.
