Ukraine's President Petro Poroshenko has announced an extension of the sanctions list of Russian companies and individuals involved in one way or another in the violation of the territorial integrity and sovereignty of Ukraine, according to the head of state's official site.

"The restrictive measures will apply, in particular, to Russian defense companies, financial institutions providing support for the terrorist organizations, i.e. the LPR/DPR [Luhansk and Donetsk people's republics], sea and air transport companies working with the occupied part of Ukraine, in Crimea. The measures will also apply to operators, vessels and aircraft which brazenly violate the Ukrainian laws by visiting the ports despite the harsh ban issued by Ukraine," Poroshenko told the National Security and Defense Council (NSDC) on Friday.

The issue has already been worked through by the Cabinet, the National Bank, the Ukrainian Security Service and other agencies, the president said.

The president also suggested adding to the sanctions names of the Crimeans taking part in Russia's State Duma elections. "We must agree that the people who will be proclaimed so-called winners in the illegal State Duma elections in Crimea, which will be held on September 18, should take a worthy place on the sanctions list," Poroshenko said, adding that, "it is an honorary ticket to the sanctions club."

The president instructed NSDC Secretary Oleksandr Turchynov to update the sanctions list by adding those who will get elected, as well as members of election commissions and participants in the voting process.
