The changes will come into force on Monday, May 23, according to a decree published on the website of DPR leader Denis Pushilin.
The authorities of the Lugansk People’s Republic (LPR) also issued a decree on Saturday, saying that the exchange rate of the ruble against the hryvnia will be set at two Russian rubles for one Ukrainian hryvnia, starting May 23.
Last month, the Ukrainian National Bank (NBU) said that inflation in Ukraine may exceed 20 percent by the end of this year due to Russia’s special military operation in the country. NBU and the Ukrainian government have taken measures to deter an increase in prices, including temporarily fixing the hryvnia exchange rate.
"Our duty is to our country. We must stick to the decisions written down by the National Security Council as close as we can and for as long as we can," he told TV Pink on Saturday.
Serbia voted with the majority of the UN Human Rights Council last month to suspend Russia from the group over Ukraine. In return, the European Union exempted Serbia from its sanctions on Russian oil and gas imports.
Vucic told TV Pink that his administration had partially backed EU sanctions on Belarus. He said it endorsed nine of the 25 measures brought forth by the Council of the European Union on April 8.
"We do not rule out that someone could still be hiding there… We’ve been looking through every room, every corner. I have no doubt that we will find whoever may still be there," Denis Pushilin said on Russian television.
The Russian Defense Ministry said on Friday that the steel plant in the southeastern port city of Mariupol had been liberated from Ukrainian troops, ending a monthlong standoff. A total 2,439 servicemen have been captured since May 16.
Pushilin said six Ukrainian personnel died in a failed attempt to detonate huge ammo depots on the steel works' grounds after the majority of their fellow troops gave in. Four others were seriously wounded.
"A total of 1,396,798 people, including 234,762 children have been evacuated since the start of the special military operation," Col. Gen. Mikhail Mizintsev told a news briefing.
Russian bomb squads cleared more than 76 hectares of unexploded ordnance in the eastern regions in the past day, destroying 1,659 explosive devices.
More than 21,500 tonnes of humanitarian assistance has been delivered to those in need in Ukraine since early March, Mizintsev estimated. The aid included essentials, food, medicine and medical equipment.
"In response to further sanctions against Russia announced by the Canadian authorities, which affected not only the country's leadership, military and business circles, but in some cases the closest relatives of those who have been added to the 'black list,' entry into Russia is permanently closed for a similar category of Canadian citizens," the ministry said in a statement.
"New countermeasures will soon follow in response to the hostile actions of Canadian Justin Trudeau's regime, who uses a militant Russophobia to good advantage. The additions to the Russian 'stop list' will be announced publicly," the ministry said.
"Gazprom supplies Russian gas for transit through the territory of Ukraine in the amount confirmed by the Ukrainian side through the Sudzha station - 45.9 million cubic meters as of May 21. The application for the Sokhranivka station was rejected", Gazprom spokesman Sergei Kupriyanov told journalists.
"Gazprom has completely stopped supplying gas to Gasum (Finland) due to non-payment in rubles," the company said in a statement, adding that it has yet to receive payments for gas delivered in April.
