"It was a first baby step in right direction... We did take part, we did support it," Amir Hossein Zamaninia, deputy oil minister for trade and international affairs, told reporters in Tehran, adding that Iran's current oil output is 3.85 million bpd, and its exports more than 2.2 million bpd.
Zamaninia said the exact levels of production by each country would be negotiated at OPEC next formal meeting in November, reports Reuters.
"We will make the decision depending on the process in November when we get together to discuss shares of OPEC," he told reporters in Tehran.
