Iran is planning to export natural gas to Oman through a subsea pipeline.
Prior to the Tuesday talks Zangeneh expressed optimism that the talks would bear favorable results for the two countries.
"We regard Iran more than a commercial partner and see it as a friend and a brother country," said Al Rumhy for his part before the talks began in Tehran.
He also said that the talks between Iranian and Omani experts in recent months over the gas projects have gone well.
"We are here today to hold more talks about the project," said the Omani official.
Based on an agreement signed in 2013, Iran will export 28 million cubic meters of gas to Oman per day for a period of 15 years through a pipeline that will go to the sultanate through the Persian Gulf.
Almost a third of the gas exported by Iran to Oman will be turned into liquefied natural gas (LNG) in the sultanate’s Qalhat plant, and the rest will be consumed domestically.
Iran will accordingly use the LNG produced at Qalhat plant for exports to European and Asian markets.
In October, experts from Iran and Oman held talks with representatives of Royal Dutch Shell, Total and South Korea’s Korea Gas Corporation (KOGAS) in assessment of the gas project.
