The Trilateral Contact Group, comprising Russia, Ukraine and the Organization for Security and Co-operation in Europe (OSCE), is working toward a diplomatic resolution of the ongoing armed conflict in Ukraine.
"The security subcommittee should discuss the framework for deploying in Ukraine a combined [peacekeeping] mission on civil and military aspects under the EU and EU aegis," he said.
President Poroshenko also said that the Russian side had not objected to a peacekeeping mission in Ukraine during the latest Normandy-format talks on the settlement of the Ukraine crisis.
He added that a peacekeeping mission to crisis-hit eastern Ukraine should not supplant or cancel the Minsk II ceasefire agreements, signed in mid-February following the marathon Normandy-format talks in Minsk.
Normandy group includes Russia, Ukraine, Germany and France.
President Poroshenko underscored that a possible peacekeeping force should operate alongside the monitoring mission that is currently carried out by the OSCE.
The OSCE mission, which is unarmed and civilian, is tasked with observing and verifying ceasefire implementation.
The OSCE mission also assisted in the pullout of heavy weaponry by the Kiev forces and the militia of the self-proclaimed Luhansk and Donetsk republics in Ukraine's east.
According to UN estimates, over 6,000 people have been killed in the conflict that erupted in April 2014.
