Given the production restraints in some countries, the one million barrels per day proposal would in reality end up adding several hundred thousand barrels to the market.
Since its December 2016 oil production-cut deal came into effect, the Organisation of Petroleum Exporting Countries (OPEC) has seen crude oil prices more than double, following the market rebound from the lows of early 2016.
The proposal is the result of a face-saving compromise hammered out after days of diplomacy in Vienna dominated by tensions between Iran and archfoe Saudi Arabia over amending an 18-month-old supply-cut deal that has lifted oil prices to multi-year highs.
Al Jazeera's Paul Brennan explains why.
The increase was announced after ministers from the group met on Friday in Vienna.
And despite the push for wider production growth of 1 million barrels per day (bpd), actual output increases of around 600,000bpd are being forecasted due to the fact other OPEC member states can not grow their supplies.
How that translates into effective production increases is uncertain, as some OPEC countries can not easily ramp up production. Iran said the real increase could amount to as little as 500,000 bpd. "We're taking our breath and focusing on the oil market", said Ryan Detrick, senior market strategist at LPL Financial in Charlotte, North Carolina.
Iran, OPEC's third-largest producer, had demanded OPEC reject calls from Trump for an increase in oil supply, arguing that he had contributed to a recent rise in prices by imposing sanctions on Iran and fellow member Venezuela.
"Some of the countries. are not going to be able to produce, so the others will".
Crude oil prices are rising sharply, extending weekly gains.
The production limits by the Organization of the Petroleum Exporting Countries and Russian Federation since 2016 have helped increase oil prices, with the benchmark USA crude contract hitting its highest level in more than three years in May.
The group's communique still pledged a return to 100% compliance with the original 2016 agreement - ending a period of deeper-than-intended cuts - but Al-Falih insisted that no individual country will be subject to a strict output cap. Furthermore, 7 out of 12-member states saw their supply-flows fall more than the designated set levels by OPEC, bolstering the compliance rate above the set 1.2mbpd target to over 1.9mbpd.
Iran has objected to having members with additional capacity such as Saudi Arabia fill Venezuelan output gaps.
He also warned the world could face a supply deficit of 1.8 million bpd in the second half of 2018 and that it was OPEC's responsibility to alleviate consumers' concerns.
