* Brent hits highest since February
* Iran to keep oil exports at around 2.6mn bpd
* Major producers confirm global inventories falling
* Russia seeks cooperation beyond end of next March
* WTI discount to Brent widest since August 2015

Oil prices rose on Monday to their highest in seven months after major producers said at a meeting in Vienna the global market was well on its way towards rebalancing.
The November Brent crude futures contract was up 35 cents at $57.21 a barrel by 0927 GMT, its highest since February 23.
US crude for November delivery was down 8 cents at $50.58, but not far off recent four-month highs.
The Organisation of the Petroleum Exporting Countries, Russia and several other producers have cut production by about 1.8 million barrels per day (bpd) since the start of 2017, helping lift oil prices by about 15% in the past three months.
Kuwaiti Oil Minister Essam al-Marzouq, who chaired Friday's meeting in Vienna of the Joint Ministerial Monitoring Committee, said output curbs were helping cut global crude inventories to their five-year average, Opec's stated target.
Russia's energy minister said no decision on extending output curbs beyond the end of March was expected before January, although other ministers suggested such a decision could be taken before the end of this year.
Iran expects to maintain overall crude and condensate exports at around 2.6 million bpd for the rest of 2017, a senior official in the nation's state oil company said, while the UAE's energy minister said its compliance to supply cuts was 100%.
Nigeria is pumping below its agreed output cap, its oil minister said.
"On the basis of the current IEA estimates, the oil market is more or less balanced in the second half of the year," said Commerzbank in a note. "For stocks to be reduced any further, however, the oil market would have to show a deficit, so the optimism appears exaggerated."
Opec's production cuts have been met with rising US shale oil output, which has tempered the rise in US oil prices relative to the increase in Brent futures.
The discount of the benchmark WTI crude contract to Brent futures rose to $6.65, the widest since August 2015. This gap has doubled in the last six weeks, as US crude demand has been undermined by hurricane damage to US refineries.
US energy firms cut the number of oil rigs operating for a third week as a 14-month drilling recovery stalled. Investors were also eyeing developments in North Korea. US Treasury Secretary Steve Mnuchin on Sunday said President Donald Trump wants to avoid nuclear war with North Korea.
