North Korea needs tests to ideal its missile program, but it also is thought to stage its launches after the elections of new US and South Korean presidents in an attempt to gauge a new administration's reaction. That's far enough to reach the US military base in Guam.
That missile, launched April 29, blew up over land in North Korean territory, according to a spokesman for the US Pacific Command.
This latest test comes only days after the South Korea elected President Moon Jae-in, who has said he will aim to improve ties with Pyongyang.
South Koreans watch a television displaying news broadcasts reporting on North Korea's recent ballistic missile launch, at a station in Seoul, South Korea.
Moon, unlike his conservative predecessors, advocates reconciliation with Pyongyang but warned Sunday that dialogue would be possible "only if the North changes its attitude".
Since Trump became president in January, CNN said, North Korea has attempted at least nine missile launches on six occasions.
"Commenting on the CIA's decision to create a Korea Mission Center, John Dunn described it as "the beginning of the Trump Administration's actual response to North Korea" and the sign that the North Korean problem got worse".
The US ambassador to the United Nations, Nikki Haley, has accused North Korean leader Kim Jong-un of being in a "state of paranoia", following another ballistic missile test.
She said it was time to "send a strong, unified message that this is unacceptable, and I think you'll see the global community do that".
"U.S. and South Korean military officials are still assessing what type of shorter-range missile this one was".
The US, concerned by North Korea's rapidly-developing missile and military nuclear programs, has sent a strike force to the peninsula.
How are US-North Korea relations?
This undated picture released from North Korea's official Korean Central News Agency (KCNA) on May 5, 2017 shows North Korean leader Kim Jong-Un (C) inspecting the defense detachment on Jangjae Islet and the Hero Defense Detachment on Mu Islet located in the southernmost part of the waters off the southwest front.
Both Moon and Japanese Prime Minister Shinzo Abe immediately condemned the launch, with Moon expressing "deep regret" that it occurred shortly after the new government was sworn in.
Earlier, Japanese officials said the missile landed in the Sea of Japan but outside the country's exclusive economic zone.
Given how close the missile came to Vladivostok, the White House's statement following Sunday's launch unsurprisingly referenced Russian Federation. Delegations from the United States, South Korea and North Korea are also there. Trump has called North Korea a "flagrant menace" and urged for "far stronger sanctions".
Outside militaries will closely analyze what the North fired.
The launch of the as yet unidentified missile could signal advances over known North Korean capabilities, adding to tensions in the region as the Trump administration seeks to prevent Pyongyang from developing an intercontinental ballistic missile capable of reaching the US mainland. Past North Korean missiles have flown farther than Sunday's test, landing closer to Japan, but this launch follows a series of high-profile failures.
Inada's remarks suggest the missile might have been on a "lofted" trajectory, meaning it could have a far longer range than it actually flew.
Experts said the altitude reached by the missile tested on Sunday meant it was launched at a high trajectory, which would limit the lateral distance it traveled.
"North Korea's missile launch is a serious threat to Japan and clearly violate against the United Nations resolution".
Russia's ballistic missile launch early warning system (SPRN) detected the launch form North Korea at about 08:30 GMT on Saturday, the ministry said.
Other Americans in the group included Thomas Pickering, a former USA ambassador to the United Nations and a former undersecretary of state, and Robert Einhorn, a former U.S. special adviser for nonproliferation and arms control in the State Department. Trump has vowed not to let that happen.
Referring to North Korea, he remained downbeat about the current USA and South Korean leaders' ability to resolve what he described as a "really tough sort of problem".
The aircraft carrier USS Carl Vinson is now in exercises with South Korean navy ships in waters off the Korean Peninsula.
On Saturday, a top North Korean diplomat said Pyongyang was open to dialogue with the Trump administration under the right conditions.
"They are telling us they don't support OBOR and sabotaging our relationships with other countries", he said.
