According to the country's semi-official Fars news agency, Brigadier General Hossein Salami said that Iran has maintained current limits on its missile capabilities due to a "strategic doctrine".
"If we have kept the range of our missiles to 2,000 kilometres, its not due to lack of technology," Brigadier General Salami was quoted as saying. "We are following a strategic doctrine".
"So far we have felt that Europe is not a threat, so we did not increase the range of our missiles," he added. "But if Europe wants to turn into a threat, we will increase the range of our missiles."
Despite US President Donald Trump calling on his allies, including European nations, to take a stronger stance on Iran and to scrap or amend the 2015 nuclear accord, European states have tended to tread more carefully in dealing with Iran.
The deal, signed during Barack Obama's time as US president, granted Iran sanctions relief in exchange for increased controls and monitoring of its nuclear programme.
Unlike the US, European signatories of the deal have maintained that Iran has acted in accordance with the accord.
Earlier this month, however, Tehran accused France of stoking Middle East tensions after French Foreign Minister Jean-Yves Le Drian criticised Tehran's "hegemonic" ambitions in the region.
Iran has repeatedly insisted that its missiles programme is for defence only.
According to remarks made by the head of Iran's Revolutionary Guards in October, Iran has the capabilities to strike targets within 2000km (1240 miles).
Major General Mohammad Ali Jafari said that this range includes "most of American interest and forces".
