In a statement issued today, the White House press secretary points out that the missile landed closer to Russian Federation than to Japan.
The statement says the United States maintains its "ironclad commitment" to stand with its allies in the face of the serious threat posed by North Korea.
"The remark is definitely a bit softer in tone compared to the past when the North would've said no to talks unless the US acknowledges them as a nuclear power".
The projectile launch comes two weeks after a ballistic missile test that South Korean and U.S. officials said failed.
"Australia regards this as a reckless and provocative action that leads to instability both regional and globally and has condemned clearly in the past North Korea for this sort of behaviour and we do so again", Defence Minister Marise Payne told reporters in Melbourne on Sunday.
Despite South Korean and US assurances that the deployment is defensive, China considers the system's powerful radar a threat to its security.
An undated file photo released by the North Korean Central News Agency on 7 March 2017 shows four projectiles during a ballistic rocket launching drill at an undisclosed location.
The launch also comes as troops from America, Japan and two European nations gather on remote USA islands in the Pacific for drills that are partly a message to North Korea.
China's foreign ministry has expressed opposition to North Korea's test-launch of a ballistic missile and called on all sides to exercise restraint.
The North has conducted five nuclear tests despite United Nations sanctions and is also developing long-range missiles.
Trump was briefed on the launch, the White House said in a statement late Saturday.
North Korea launched the Pukguksong-2 missile, an upgraded, extended-range version of its submarine-launched ballistic missile (SLBM), from the same Kusong site on 12 February.
Yoon quoted Moon as saying South Korea is "leaving open the possibility of dialogue with North Korea, but we should sternly deal with a provocation to prevent North Korea from miscalculating".
Just one day before the launch, a North Korean diplomat said that the country's leader, Kim Jung-Un, would be willing to hold talks with the U.S. "under the right conditions". But it flew for about 30 minutes - a much longer time than would be required using a standard trajectory.
The missile launch comes days after North Korean officials announced their aims to launch a "series of powerful anti-terrorist" strikes against President Donald Trump's free world.
The Rodong Sinmun, the official newspaper of the ruling Workers' Party, said the regime will continue building up its military for stronger self-defense as "the imperialist USA and its followers are notching up pressure on us" and "driving the situation of the Korean Peninsula out of control by warmongering".
As CNN points out, this is the 10 attempted missile launch since Trump was inaugurated in January.
There has been mounting speculation that Pyongyang will conduct an intercontinental ballistic missile test after Kim used a New Year's Day address to claim that the North was in the "final stages" of developing such a weapon.
