"Extant historical documents, printed works housed in libraries across the world, manuscripts, maps and films which mention the name of the 'Persian Gulf' all prove that the Persian Gulf belongs to Iran," Chairman of the parliament's Cultural Commission Gholam Ali Haddad Adel said on Friday.
The lawmaker stated that instead of damaging Iran, such measures further discredit Iran's enemies.
"The more they try to oppose Iran, the more powerful the Islamic Republic becomes," Haddad-Adel added.
He noted that such measures to oppose the Islamic Republic were "childish and illogical."
While historical documents show that the waterway has always been referred to as the 'Persian Gulf', certain Arab states have recently mounted efforts to remove 'Persian' from the name of the waterway.
In early 2010, the Riyadh-based Islamic Solidarity Sports Federation cancelled sports events after Iran used the term "Persian Gulf" on medals for the event it was seeking to host.
Iran designated April 30 as the National Persian Gulf Day to highlight the fact that the waterway has been referred to by historians and ancient texts as 'Persian' since the Achaemenid Empire was established in what is now modern day Iran.
In July 2009, archeological excavations in the Iranian port city of Siraf yielded new evidence confirming the antiquity of the Persian Gulf title.
The Iranian archeologists discovered Sassanid and early-Islamic residential strata as well as a number of intact amphoras used in sea trade during the Parthian, Abbasid and early Islamic eras, all referring to the waterway as the Persian Gulf.
