RIYADH: Saudi Arabias King Salman and Russian president Vladimir Putin voiced their support for continued coordination on the global energy markets, the Kremlin said on Tuesday, after the two leaders had a telephone conversation. The Kremlin also said the two leaders praised the ongoing bilateral cooperation between Russia and Saudi Arabia. "Mutual attitude for further strengthening of multifaceted Russia-Saudi Arabia ties has been expressed," the Kremlin said. Russia, other leading oil producers and the Organization for the Petroleum Exporting Countries (OPEC) agreed to cut their oil output by a combined 1.2 million barrels per day starting from January in order to balance global oil markets and support prices. The next ministerial OPEC and non-OPEC meeting is due to be held in Vienna in mid-April.
