UPDATE 1-OPEC's Barkindo calls for cooperation between OPEC and non-OPEC countries
Iranian Oil Minister Bijan Zanganeh said on Sunday he hoped decisions taken by the OPEC and the non-OPEC ministerial committee would not be affected by comments made by the U.S. President Donald Trump on oil producers.
OPEC and its allies reduced oil output in August as a drop in Iranian supply due to U.S. sanctions.
Global energy demand is expected to grow by 33 percent to 2040, the Secretary-General of the Organization of the Petroleum Exporting Countries, Barkindo said, citing the group's long-term world oil outlook, released on Sunday.
Oil would continue to have a predominant role in the energy mix for the foreseeable future, Barkindo said during a question and answer session.
