Recently, various international bodies and experts verified the fact that the earth observation satellite Kwangmyongsong-4 was launched to use space for peaceful purposes from A to Z.

A doctor at a cosmophysics center of the U.S. on March 10 said that a satellite of north Korea is going round the earth along its orbit, acknowledging the credibility of the assertion that it is an earth observation satellite.

Its orbit is clearly displayed on the website tracking the satellite in real time on the basis of the data sent by the North American Aero-space Defense Command.

Nevertheless, the U.S. is still describing the DPRK's satellite launch as a "provocative act of escalating tensions", terming it a "long-range missile" test-fire. This is, indeed, a far-fetched assertion.

The DPRK's activities for developing outer space for peaceful purposes were compelled to cover an untrodden difficult path owing to the U.S. and other forces disturbing them.

The U.S. and other hostile forces, regarding the DPRK, an independent country, as a thorn in their flesh, used to term its satellite liftoff for peaceful purposes a "long-range missile" launch and force the UN to meet their brigandish demands.

No article of the UN Charter allows the UNSC to deprive any country of its right to peaceful use of outer space stipulated in international law.

Should the DPRK's satellite launch be called into question, all the countries including the U.S. which launched satellites should be taken to task. History records more than 9 000 satellite launches but the UNSC has never adopted a resolution banning them, except for the DPRK's satellite liftoffs.

What merits a serious attention is that the U.S. launched intercontinental ballistic missile Minuteman-3 in its mainland recently.

Reuters reported that the U.S. test-fired Minuteman-3 against the backdrop of the escalating tension in Korea, adding that its test-fire totaled 15 since 2011.

The U.S. should give up its sinister attempt to deprive the sovereign state of its independent and legitimate right and immediately stop its brazen-faced action against satellite launches for peaceful purposes.
