Mr Hyon added: “We are planning to develop the Earth observation satellites and to solve communications problems by developing geostationary satellites.
“All of this work will be the basis for the flight to the moon.”
He said he would like to see the work happen "within 10 years' time."
The comments emerged a day after North Korea launched a missile that landed in Japanese waters, which prompted the US to warn it was ready to defend "ourselves and our allies".
