Longer-range ballistic missile tests, banned by the United Nations and seen as threatening by surrounding countries, would likely result in more sanctions.
Washington and Japan have both described Thursday's launch as "short-range ballistic missiles", although acting White House chief of staff Mick Mulvaney told CBS it was "a very non-provocative provocation".
"The debris generated by the launch in North Korea is a virtual match of a launch of Iskander conducted by Russian Federation", it said.
The missiles were short-range and the launches do not mean Kim has made a decision to end his self-imposed moratorium on testing long-range missiles that could reach the United States mainland.
According to US President Trump, the talks failed because Kim demanded too much.
He said the weapons were smaller, short-range missiles, but added: "Nobody's happy about it".
Even so, Moon said he saw the tests as a sign that North Korea wanted to negotiate, and said he planned to push for a fourth inter-Korean summit with Kim.
It said Pyongyang was believed to have test-launched two short-range missiles, which were estimated to have flown around 420 km and 270 km. Seoul and Washington previously held large-scale military exercises in the spring, but this year chose to scale those back to "reduce tension" with North Korea.
However, given North Korea's longstanding missile technology relationship with the China Aerospace Science and Industry Corporation (CASIC), and this new SRBM's similarity to a new CASIC missile, there is also a possibility that Pyongyang's new SRBM was assisted by China.More news: Los Angeles Lakers' LeBron James stunned by Magic Johnson's 'weird' exit
The deal was in discussion for during peace talks in Hanoi earlier this, which ended in failure after President Donald Trump walked away after two days of discussion.
In Geneva on Thursday, North Korean Ambassador Han Tae Song likened the economic sanctions to "crimes".
"The test comes as U.S. envoy on North Korea Stephen Biegun is visiting Seoul", NPR's Anthony Kuhn reports from South Korea's capital, "and defense officials from the U.S., Japan and South Korea are holding annual talks here, as well".
So far, the prime minister has stated that a bilateral meeting with Kim "must be a meeting that can be conducive to resolving the abduction issue".
Before Donald Trump met with Kim Jong Un at a summit in Hanoi in February, the North Korean dictator reportedly asked the United States to send over "famous basketball players" as part of a "cultural exchange" between the two countries as they attempted to craft a denuclearization agreement, per an ABC News report.
U.S. secretary of state Mike Pompeo has insisted a deal onnuclear disarmament with North Korea is was still possible. Then the USA revealed that it seized a North Korean cargo ship, used to export coal in violation of economic sanctions.
Though confirmation of foreign assistance for North Korea's new SRBM likely will have to await disclosures by the South Korean or US governments, CASIC's longstanding missile technology relationship with North Korea, and the new SRBM's similarity to CASIC's CM-401, point to the possibility of a significant Chinese role in North Korea's new SRBM.
The missile test was the second such move in less than a week, and came from the Sino-ri missile base, located around 130 miles north of the border between North and South Korea.
The official Korean Central News Agency reported the following day that Kim himself supervised the latest missile test, the second since breaking a 522-day pause on such activities earlier this week.
