While Iran has voiced skepticism in recent days about the prospect of a production increase, on Friday it sounded more flexible on the idea.
Benchmark oil prices have already risen by around 70 percent over the past year, which should help restrain consumption growth.
The actual output increases set a bullish tone, as they came in below some of the highest figures that had been discussed prior to the meeting. "Need to keep prices down!" he said in a tweet. The cartel would be the biggest beneficiary of possible Chinese tariffs on USA oil imports, as these could help it regain market share, OPEC sources and industry officials tell Reuters.
In another escalation, India on Thursday joined China and the European Union by increasing duties on various commodities imported from the United States.
For Opec, over-compliance with its supply-cutting deal is a nice problem to have.
Two OPEC sources said the group agreed that OPEC and its allies led by Russian Federation should increase production by about 1 million barrels per day (bpd), or 1 per cent of global supply. Iraq said the real increase would be around 770,000 bpd because several countries that had suffered production declines would struggle to reach full quotas.
The new deal would effectively roll back the deeper-than-intended cuts from nations such as Venezuela, returning the curbs back to the level originally agreed in 2016, the delegate said.

"It was deliberate ambiguity", said Helima Croft, global head of commodity strategy at RBC Capital Markets.
"If the volume of spare capacity goes down then the market gets much more vulnerable to supply shocks", said Essner, the Nasdaq analyst.
The cartel has overcome opposition from Iran and will raise output by one million barrels per day. Likewise, the oil for delivery in far-month August traded higher by Rs 6 or 0.13 per cent at Rs 4,489 per barrel in 118 lots.
Falih has warned the world could face a supply deficit of up to 1.8 million bpd.in the second half of 2018 and that OPEC's responsibility was to address consumers' worries.
Nigerian Energy Minister Emmanuel Kachikwu said that supply was ultimately likely to increase by 600,000 to 700,000 barrels a day.
"Reallocating (output) to other countries like Saudi Arabia may be a technical solution but it may not be politically acceptable to others", he said.
