Iran's Foreign Ministry spokesman Hassan Qashqavi said on Monday that Iran's missile program was not related to that of Democratic People's Republic of Korea (DPRK), the local Press TV website reported.
"There is absolutely no relation between the two countries. North Korea launched its space program several years ago and has fired rockets into space many times," said Qashqavi.
However, he warned against any move that would provoke instability in a "sensitive region such as Eastern Asia," the report said.
Recently, Iran's Embassy in Tokyo also rejected the report by the Japanese daily Sankei Shimbun that "A 15-member Iranian delegation had gone to North Korea in March to counsel Pyongyang on rocket technology."
The DPRK's official media reported Sunday that the country successfully launched a rocket carrying the "Kwangmyongsong-2" communications satellite which entered orbit 10 minutes after launch.
Earlier in February, Tehran also announced that the Omid lightweight telecommunications satellite, its first home-made satellite, was successfully sent into space by the Iranian-produced satellite carrier Safir 2.
The U.S. administration of President Barack Obama linked the new Iran's developments with its nuclear disputes and viewed Tehran's efforts to develop nuclear capability and to sponsor terrorism as "acute concern."
