"We hope to see an end to the issue before the end of the year," Mottaki told a press a conference when asked about demarcating the sea border which includes the offshore Dorra gas field.
"We are seriously studying the issue and it has been decided that concerned committees will meet before the end of the year. Legal advisors from the two countries are also studying the issue," he said.
The dispute dates back to the 1960s when Iran and Kuwait awarded offshore concessions to the former Anglo-Iranian Petroleum Co, now part of BP, and Royal Dutch/Shell that overlap in the northern part of the Dorra field.
Recoverable gas reserves from Dorra are estimated at some 200 billion cubic metres (seven trillion cubic feet).
Mottaki also said that he had agreed with Kuwaiti counterpart Sheikh Mohammad al-Sabah to revive the issue of exporting Iranian natural gas to the emirate.
In March 2005, the two countries signed a seven-billion-dollar 25-year deal under which Iran will supply some nine million cubic metres (300 million cubic feet) of natural gas a day to Kuwait.
Delivery was scheduled to begin in 2007 but the project has been delayed for reasons which have not been made clear.
Mottaki is on a tour of Gulf states and has already visited Qatar and Oman.
