The statement was published ahead of the Second World Congress of Crimean Tatars that started on Saturday in Turkey's capital Ankara.
"Our plans include the development of a program to provide Crimea — the historic homeland of the Crimean Tatars — the status of national and territorial autonomy within the Ukrainian state," Poroshenko said.
Earlier it was reported that the Ukrainian President promised to return Crimea, which in the spring of 2014 re-united with Russia following a referendum.
The Black Sea peninsula called a referendum following a bloody uprising in Kiev, hailed by the Western governments as a "democratic revolution," although there was nothing democratic about it. After all, "forceful ousting of an elected president amounts to a coup," the daily observed.
In March 2014, more than 96 percent of Crimeans voted in favor of splitting with Ukraine and joining Russia.
