Extending warm congratulations to the supreme leadership of the DPRK and scientists and technicians of its Academy of Defence Science on the successful test-launch, the Russian Group for Solidarity with the DPRK said in its statement:

Under the wise guidance of respected Marshal Kim Jong Un, the Korean people are creditably carrying out the tasks set forth by the Workers' Party of Korea.

U.S. President Trump, pursuing the policy of his predecessors, had a wrong understanding of the Korean people.

The U.S. has posed military threats to the DPRK by endlessly sending nuclear strategic assets to the Korean peninsula, but the DPRK developed the ICBM and succeeded in its test-launch.

Now that the DPRK has ICBMs and nuclear weapons capable of striking the U.S. mainland, the U.S. can no longer check the DPRK's peaceful development.

The Moscow Group for the Study of the Juche Idea said in its statement that the said DPRK's success rocked the whole world, adding:

The successful test-launch became a great turning point in bolstering up the national defense capability of the DPRK.

It has the strongest weapon capable of striking any part of the world.

We fully support all the steps taken by the DPRK to beef up its military capability.
