Ukraine is set to close the border with Russia to prevent any armed men from infiltrating into its territory.

      According to an aide of the Interior Ministry, Anton Gerashchenko, Kiev authorities are working out a number of steps to block any male Russians from getting inside Ukraine.

      Earlier, Russia-IC reported that Ukraine’s Prime Minister went public to reject the $100 discount for gas supplies.

      According to Arseny Yatsenyuk, Kiev demands a change in the contract and will not fall into ‘traps’ set by Moscow.

      The Ukrainian and Russian minister are now holding negotiations on the price in Brussels.

      The previous round of talks that took place on June 9 in Brussels didn’t lead to any breakthroughs.

      Gazprom issued a warning it would switch to advance payments with Ukraine after June 16 if it fails to repay its mounting debt currently standing at almost 5 billion, according to the Russian gas giant.

      In May, Russia signed an historic deal with China on natural gas supplies with a view to diversify its exports amid similar calls in Europe.

      The exact price has not been disclosed but it’s been reported that the 30-year contract for the supplies of 38 billion cubic meters of gas could bring Russia as much as $400 billion.

      Elsewhere, Lithuania's competition council has fined Gazprom a whopping $48 million for allegedly preventing competition in the Baltic state where the Russian gas monopoly is the sole supplier.

      Gazprom is facing another investigation into a possible breach of competition rules in the EU.
