Iran confirmed on Wednesday that it had tested a ballistic missile, but denied that was a breach of its 2015 nuclear deal with world powers.
The comments from Defence Minister Hossein Dehghan came after the UN Security Council met yesterday to discuss the weekend test, which Washington described as "absolutely unacceptable".
"The action was in line with boosting Iran's defence power and is not in contradiction with the JCPOA (the nuclear deal) or Resolution 2231," Dehghan said.
He was referring to a UN Security Council resolution that bans Iran from developing missiles that can carry nuclear warheads.
"This test was in line with our ongoing programmes," Iranian media quoted him as saying.
"We have previously announced that we will execute the programmes we have planned in production of defence equipment meant for our national interests and objectives. Nobody can influence our decision.
"We will not allow foreigners to interfere in our defence affairs."
