The worlds top two crude-oil producers pledged to cooperate to stabilize world market, while failing to announce any specific measures to bolster prices.

We have a number of tools at our disposal for joint actions, Russian Energy Minister Alexander Novak said Monday following a meeting with his Saudi counterpart Khalid Al-Falih at the G-2 0 summit in China. Both agree that an output freeze would be the most constructive instrument, he said.

Despite promise of a significant announcement — leading to a 5.5 percent jump in oil prices — no concrete actions were uncovered at the joint press briefing in Hangzhou. Al-Falih denied there was any current need to cap production, saying marketplaces are trending in the right direction.

Brent petroleum added 11 cents to $47.74 a barrel at 12:40 p.m. Singapore time Tuesday. The global benchmark pared gains Monday to close up 1.7 percent. Russian President Vladimir Putin said last week hed like OPEC and Russia to agree on an output freeze, boosting speculation that members of the Organization of Petroleum Exporting Countries and other major producers might strike such an accord at talks this month in Algeria.

At first appearance it sounds a little bit as new wine in old bottles, Axel Herlinghaus, senior commodities analyst at DZ Bank AG, said by e-mail. In the past “there werent” lack of ambitious proclamations, but a lack of decisive follow-up actions.

Rare Briefing

While Russian-Saudi cooperation is yet to yield firm steps toward steadying the market, a joint press conference between the two oil giants is rare. It shows a growing trust and understanding that collaboration is vital to oils recovery, the ministers said.

In a joint statement, the two countries confirmed theyll hold further talks during the International Energy Forum in Algiers this month. Theyll also coordinate a bilateral working group on oil and gas cooperation in October and meet at the OPEC ministerial summit in Vienna in November.

Potential freeze words will be discussed in September, Russian news service RIA Novosti reported, citing Novak. Russia would be ready to join an agreement to cap output at the level of any month in the second half, the minister said, while Al-Falih insisted hell work with OPEC members to come to a joint understanding on coordination.

“We still cannot shoulder the shared responsibility alone; we will play the leadership role and we will catalyze others to join in, ” Al-Falih said. We are optimistic that the Algiers meeting would offer a quorum.

Several OPEC countries voiced their support for the Russian-Saudi pledge to cooperate. The oil ministers of the United Arab Emirates, Kuwait and Qatar welcomed the joint statement, while Algerian Energy Minister Noureddine Bouterfa said it depicts producers must reach an accord on output.

Oil below $50 is not acceptable, Bouterfa said. Countries need income to invest, to develop production and industries.

Russia and Saudi Arabia are considering the possibility of restriction output for three to six months, or maybe longer, RIA Novosti reported, citing Novak.

A freeze proposal was derailed in April over Saudi Arabias insistence that Iran participate. Yet the effect of the prolonged slump in crude prices — stuck at half the levels insured two years ago — has pushed oil-market rivals to collaborate.

Irans Return

Putin has said petroleum producers now recognize that Iran, which has mostly restored the output halted during three years of trade restrictions, deserves to complete its return to world markets.

Iran presented Monday that its ready to pump more crude, with state-run National Iranian Oil Co. saying the country can raise production to 4 million barrels a day in two to three months from the current daily level of about 3.8 million.

Russia and Saudi Arabia share the similar view that Iran should be allowed to reach pre-sanctions level, Novak said Monday, adding that OPEC hasnt reached a consensus on whether Iran has already reached that level of production.

While Iran ramps up, other producers including Nigeria and Libya have assured supplies disrupted in 2016 while U.S. output has declined, helping push up petroleum 70 percentage from the 12 -year lows reached in January.

Supply and demand will come more or less into balance this year, Al-Falih said. A coordinated, appropriate, collective decision on production would help bring that balance.
