 "oil, output, Opec, non-Opec nations")
Energy ministers from the Organisation of the Petroleum Exporting Countries (Opec) and non-Opec countries meeting in Vienna on Sunday have struck a positive note regarding their agreement to cut oil output as a committee set to monitor compliance with the deal meets for the first time.
"I am satisfied, I am optimistic and, as I said, the markets are on their way to rebalance and it's happening," Saudi energy minister Khalid al-Falih said.
Compliance with the agreement, which calls for cuts to begin this month, had been "fantastic", he said.
