The referendum was proposed on Monday at the forum Together with Russia.
The head of the administration of Zaporozhye Region said on Monday that the region will hold a referendum on whether to secede from Ukraine and request to join Russia.
Evgeny Balitskiy said he had signed an order to organize the plebiscite at a regional forum held in the city of Melitopol. Over 700 representatives from various parts of the Ukrainian region approved the idea, according to RIA Novosti.
Earlier in the day, administration officials indicated that the referendum could be held as soon as mid-September.
Russian forces took partial control of the region during the initial offensive against Ukraine launched in late February. The eponymous city located in the north of the region on the Dnepr River remains under Ukrainian control.
The proposal to break away from Kiev and join Russia was put to a vote by officials in Kherson Region, another Russia-controlled part of Ukraine.
Ukrainian President Vladimir Zelensky warned on Sunday that Kiev would break off all talks with Russia if the two regions go through with their plans. Moscow suggested that the Ukrainian president should address the citizens of those regions.
This is what the residents of the region plan to do. It's not like Russia is holding a referendum. Here, apparently, it is necessary to understand to whom Zelensky is addressing this statement to the citizens of Ukraine of the mentioned regions or to the citizens of Russia? If it is to the people and leadership of Russia, then we are the wrong address, said on Monday by Kremlin spokesman Dmitry Peskov.
For months, there has been no peace talks between Russia and Ukraine, as Kiev rejected such contacts and claimed it would only negotiate after defeating Russian troops on the battlefield with the help of Western military aid.
Before the talks broke off, the two nations appeared to have made progress in resolving their differences. Kiev had pledged to be a neutral country and accept restrictions on its military during a meeting in Istanbul in late March. Moscow prepared a draft peace agreement based on those proposals, but Ukraine never responded.
An indirect Russian-Ukrainian deal was mediated by the UN and Turkey last month to allow grain exports from three Ukrainian ports to resume via the Black Sea. The scheme was formalized in two separate agreements that were signed by Russia and Ukraine with the other two parties.
Russia sent troops into Ukraine on February 24, citing Kiev's failure to implement the Minsk agreements, designed to give the regions of Donetsk and Lugansk special status within the Ukrainian state. The protocols, brokered by Germany and France, were first signed in 2014. Former Ukrainian President Pyotr Poroshenko has admitted that Kiev's main goal was to use the ceasefire to buy time and create powerful armed forces. In February 2022, the Kremlin recognized the Donbass republics as independent states and demanded that Ukraine declare itself a neutral country that will never join any Western military bloc. Kiev insists that the Russian offensive was unprovoked.
