Ukrainian president Petro Poroshenko announced a fifteen-point plan for peace on 20 June.
The plan called for a week-long ceasefire, starting on 20 June, for the separatists to vacate the buildings they've occupied, for decentralization of power from the central government in Kiev, and for the protection of Russian-language rights.
The full text of the fifteen points are as follows:
Security guarantees for all the participants of negotiations.

Amnesty for those who laid down weapons and didn't commit serious crimes.

Liberation of hostages.

Establishment of a 10-kilometre (6 ¹⁄₄ mi) long buffer zone on the Ukrainian-Russian border.
Withdrawal of illegal armed formations.

Secure corridor for the escape of Russian and Ukrainian mercenaries.

Disarmament.

Establishment of units for joint patrolling in the structure of the MIA.

Liberation of illegally seized administrative premises in Donetsk and Luhansk regions.

Restoration of functioning of local government.

Restoration of central television and radio broadcasting in Donetsk and Luhansk regions.

Decentralization of power (through the election of executive committees, protection of Russian language; draft amendments to the Constitution).

Coordination of governors with representatives of the Donbas before the elections
Early local and parliamentary elections.

Program of creating jobs in the region.

Restoration of industrial objects and objects of social infrastructure.

Russian president Vladimir Putin offered some support for the plan, but called for Poroshenko to bring the separatists into negotiations.
Russian Foreign Minister Sergei Lavrov said that Poroshenko's peace plan "look like an ultimatum."
Poroshenko previously refused to enter into negotiations with armed separatists.
OSCE monitors with the Special Monitoring Mission in Ukraine met with a representative of the Donetsk People's Republic on 21 June to discuss the peace plan.
The representative said that the Republic would reject the ceasefire, and said that the primary demands of the government of the Donetsk People's Republic were "withdrawal of Ukrainian forces from Donbass", and recognition of the Republic.
However, after initial peace talks between the separatists, Ukrainian and Russian officials, and the OSCE in Donetsk on 23 June, Alexander Borodai, prime minister of the Donetsk People's Republic, said that his forces would hold to the ceasefire.
Soon after this statement, separatists in Sloviansk shot down a Ukrainian Armed Forces Mi-8 helicopter, killing all those on board.
The next day, the Office of the President of Ukraine issued a statement that said that the ceasefire had been violated by the insurgents at least thirty-five times.
President Poroshenko also said that he was considering ending the ceasefire, and Borodai said that "there has been no ceasefire".

Despite this, Poroshenko extended the ceasefire by three days from its planned ending on 27 June.
In response to this action, protesters in Kiev took the streets in large numbers to demand that the ceasefire be cancelled.
The ceasefire had little actual impact on clashes between government and separatist forces, with at least five government soldiers killed during the ceasefire.
By July, the peace plan had fallen by the wayside and Poroshenko ended ceasefire after both sides accused each other of repeated violations.
After a rocket attack that killed nineteen Ukrainian troops, Poroshenko vowed to take revenge on the separatists: "Militants will pay hundreds of their lives for each life of our servicemen.
Not a single terrorist will avoid responsibility."
