"(Such a move) will be implemented after consultations with experts," ministry spokesman Ramin Mehmanparast was quoted by Iran's parliamentary website as saying.
"The UAE maintaining these baseless claims will have a negative effect on bilateral relations," Mehmanparast stressed.
Iran and the UAE are at loggerheads over the islands of Abu Musa, Greater Tunb and Lesser Tunb, which lie in the strategic Strait of Hormuz in the Gulf.
Iran took control of them in 1971 when colonial-era Britain withdrew from that part of the Gulf.
The Islamic republic says the islands are a historic part of its territory, and President Mahmoud Ahmadinejad in April visited them to reassert that position.
However, the UAE claims ownership in line with an agreement signed with Britain, and has garnered support from other Gulf Arab states and its ally the United States.
Mehmanparast echoed Tehran's line that the UAE stance has no "rational, logical, historical, or legal basis".
Britain eventually cut direct diplomatic ties with Iran in December 2011 after pro-government demonstrators in Tehran stormed the British embassy
