Saudi Arabia's foreign minister said on Thursday it would be reasonable for the kingdom to go along with other producers in changes to oil production.
Adel al-Jubeir, speaking at an event in Tokyo, also said OPEC and non-OPEC oil producers were increasingly moving towards a common position, Reuters reported.
"I think there is a move towards a common position, towards a common effort," he said. "If other producers were to agree, it is reasonable to accept Saudi Arabia to go along with it."
Members of the Organization of Petroleum Exporting Countries are due to meet informally in Algeria on the sidelines of the International Energy Forum on Sept. 26-28, and are expected to seek to revive a global output freeze deal.
Russia is also expected to attend the IEF.
"If you want to have an impact, then all of us have to shoulder the responsibility, and I believe over the past five or six months, I believe that there has been an increasing realization that this is a collective effort," Al-Jubeir said.
Iraqi Prime Minister Haider al-Abadi said this week that OPEC's second-largest producer after Saudi Arabia would support a decision to freeze oil output to prop up prices, although the country's oil minister has said it wants to continue to ramp up production.
Iran was also sending positive signals that it could support joint action to support the oil market, sources in OPEC and the oil industry told Reuters last month.
Tehran refused to join a previous attempt this year by OPEC plus non-members such as Russia to stabilize production, and talks collapsed in April.
