John Bolton, who is the United States National Security adviser, described North Korea’s recent missile tests as violation of UN Security Council resolutions, while it is the first time a senior US official has delivered such a statement.

Bolton stated on Saturday when Donald Trump heads to Japan for talks on nuclear issue, “The UN resolution prohibits the launch of any ballistic missiles,”

North Korea’s test firings hold short-range ballistic missiles, though the Trump national security adviser considered it was “no doubt” a violation, continued asking its leader, Kim Jong-un, to return to denuclearization discussions.

Bolton’s criticism emerged on the event of the US president a four-day visit to Japan, who has been arrived on Saturday.

North Korean senior leader supervised the first flight of a previously untested weapon earlier this month, which is said to be a relatively small and fast missile on which experts say it will be easier to launch, hide, and manoeuvre in flight.

The US National Security Adviser said, “Trump has held the door open for Kim, the next step is for Kim to walk through it,” He also highlighted that his nation still offers Kim’s nation to join talks table but there was no changed came out from the one outlined at the summit in Hanoi.

Bolton also asked North Korean leader to accept the meeting with Shinzo Abe, the Japanese prime minister, which he believed could help start again dialogue on weapons programs of the Democratic People’s Republic of Korea.

He added, an Abe-Kim summit “could be substantive assistance to that,”
