As reported by Censor.NET citing Interfax-Ukraine, they announced in a joint statement.
"By using radicals, Kyiv has organized and is maintaining the railroad blockade and is threatening to block motorways connecting the Donbas republics to Ukraine," Zakharchenko and Plotnitsky said.
"We have to declare that if the blockade is not lifted by 00:00 a.m. Wednesday (March 1, 2017), we will appoint external management at every enterprise under Ukrainian jurisdiction operating in the "DPR" and "LPR"," the statement said. The terrorists also promised to stop coal supplies to Ukraine.
"We will reorganize all manufacturing processes and aim at the markets of Russia and other countries," the leaders of the militants said.
Zakharchenko and Plotnitsky also believe the transport blockade of the Donbas is at odds with the Minsk Agreements.
"It goes directly against both the spirit and the letter of the Minsk Agreements and generally characterizes this Ukrainian leadership as one unable to take care of its citizens. Many enterprises have been forced to cease operation as a result of the Kyiv authorities' criminal actions," the statement says.
On Jan. 25, anti-terrorist operation (ATO) veterans blocked the Luhansk-Popasna haul, launching a trade blockade of the occupied Donbas areas. The movement of 12 trains with a total of 700 cars has been barred.
Later, Deputy Minister for the Occupied Territories and IDPs Heorhii Tuka said the decision to launch trade blockade was extra-legal. Minister for the temporarily occupied territories and IDPs Vadym Chernysh spoke against possible ban on commodities delivery across the contact line in the Donbas: "We need to be able to deliver coal, otherwise we will face problems throughout the country."
On Feb. 2, participants of the trade blockade barred another railroad track near Bakhmut.
