"We are even ready to offer them a special status of a free economic zone with a special regime (of relations) with the European Union and Russia," Poroshenko said.
He said that the legitimate elections under Ukrainian law to be held at the Donbas and local authorities should be also elected to implement this.
He recalled that according to the law the Donbas already has a special status of local government like any other Ukrainian region.
"They already have a significant part of control. They may decide what language to speak, what songs to sing. Donbas has much of the financial sustainability (according to the law on the special order of the local government - Ed.)," he said.
"But it's not a question of people's interests, it is not a conflict between the Donbas residents and the rest of the Ukrainians - it is a question of aggression that was imposed on us from outside," Poroshenko said.
Poroshenko also said that the Ukrainian government continues to supply gas to the occupied territories in the amount of $6-7 million each day without receiving any payment.
In general, he said, the military conflict in the east costs Ukraine more than $10 million per day, which makes economic growth in the country impossible.
"It is extreme pressure on my country, and any state can ensure economic growth during such a heavy type of war, for we are fighting against, perhaps, the biggest and most efficient army on the European continent," he said.
Poroshenko also said that Ukraine expects to receive $13-15 billion over two years as a result of negotiations with international financial organizations such as the IMF and the World Bank, as well as with the governments of the US, the EU, Australia, Japan, Canada and other.
