It seems that North Korea is trying not to aggravate the situation.
Japanese authorities determined it was a ballistic missile launched from a site in Gangwon province on North Korea's east coast, Japan's NHK broadcaster and Kyodo News reported. These projectiles fired did not threaten the U.S. or Guam.
The U.S. Pacific Command issued a statement shortly after the launch, saying that one of the missiles blew up within moments of launch. They come during a joint military exercise between the United States and South Korea.
North Korea's latest released photos hint they are developing a more advanced solid-fuel ballistic missile.
The launch is the first by the North since it test-fired a missile on July 28th that could have been created to reach 10,000km, putting parts of the USA mainland within reach. That would put parts of the US mainland within reach and prompted heated exchanges that raised fears of a new conflict on the peninsula.
"The firing of any ballistic missile is a violation of UN Security Council resolutions", the secretary said. "The Ulchi Freedom Guardian exercise is a command post drill of a defensive nature that is conducted annually as part of the South Korea-U.S. alliance". The second missile launch appears to have blown up nearly immediately.
The United States and South Korea are technically still at war with the North because their 1950-53 conflict ended in a truce, not a peace treaty.
Trump has called on China to play a more active role in convincing North Korea to halt its weapons programme and stop threatening its neighbours and the US.
Pyongyang is particularly wary of the USA military's Gray Eagle, a medium-altitude, long-endurance unmanned aircraft system, because authorities think the United States could deploy it in a potential beheading operation, the Asahi reported. North Korea had refrained from missile launchings and other provocative acts since then.
Trump also expressed optimism earlier this week about a possible improvement in relations.
"We continue to want the Kim regime to understand there is a different path he can choose", Tillerson said.
South Korean President Moon Jae-in did not participate in the meeting and his office didn't immediately provide further details. In a report that lacked the North's usual belligerent threat against the United States, its official KCNA news agency quoted Kim as telling its Army that it "should think of mercilessly wiping out the enemy with arms only and occupying Seoul at one go and the southern half of Korea". Trump threatened to unleash "fire and fury" on Pyongyang if it continued to threaten the U.S. or its allies, while the communist regime hit back with threats to launch ballistic missiles toward Guam.
"Clearly they are still messaging us as well that they are not prepared to completely back away from their position", he said.
