Iranian Oil Minister Bijan Zanganeh told reporters on Monday he would support prolonging output cuts by six to nine months. Tehran has in the past objected to policies put forward by arch-rival Saudi Arabia, saying Riyadh was too close to Washington.
"I have no problem with a production cut ... It's going to be an easy meeting as my stance is very clear," Zanganeh told reporters upon arriving in Vienna.
The United States is not a member of OPEC, nor is it participating in the supply pact. Washington has demanded Saudi Arabia pump more oil to compensate for lower exports from Iran after slapping fresh sanctions on Tehran over its nuclear program.
OPEC and its allies led by Russia have been reducing oil output since 2017 to prevent prices from sliding amid soaring production from the United States, which has become the world's top producer this year ahead of Russia and Saudi Arabia.
Fears about weaker global demand as a result of a US-China trade spat have added to the challenges faced by the 14-nation Organization of the Petroleum Exporting Countries in recent months.
