Ukrainian central authorities and pro-Russian insurgents announced plans to swap prisoners on Sunday, Interfax reported.
According to the report, 75 Ukrainian soldiers will be exchanged for 75 members of the pro-Russian militia.
The swap will be conducted under the agreement from Sept. 5 which stipulates that "all hostages and unlawfully detained prisoners" must be released by both sides.
The agreement was signed by members of trilateral group on Ukraine, consisting of representatives of the OSCE, Russia and Ukraine, as well as by representatives of the self-proclaimed Donetsk and Luhansk people's republics.
Last week Ukrainian President Petro Poroshenko said that since the agreement was signed, Kiev had received back 700 of its servicemen, and expects 500 more by the end of the week.
The actual exchange had not yet been reported at the time of publication.
