Not surprisingly, the Pentagon is revving up its missile defense technology and taking North Korea's nuclear threat very seriously - despite continued questions regarding the accuracy of the country's claims about its nuclear arsenal and some of its weapons capabilities.
But in addition to the statement's core message that the coalition will work to deter North Korea's nuclear and missile development programs, .the three sides also urged China to stop its retaliatory measures against South Korea over Seoul's decision to deploy the US missile defense system THAAD to the Korean peninsula.
During the 30-minute talk, they agreed on the importance of bilateral partnership regarding the growing threat from North Korea, and on the importance of incorporating U.S. military assistance into their readiness plan, the statement said. Why are we, on the far side of the Pacific, still responsible for containing North Korea when two of its neighbors - Russian Federation and China - are nuclear powers and South Korea and Japan could field nuclear and conventional forces far superior to Kim's?
After a few days of saber-rattling, US President Donald Trump's administration has reverted to the same North Korea policy as its predecessor: relying on China to control Pyongyang.
"But at the same time", the prime minister said, "dialogue for the sake of dialogue is valueless and it is necessary for us to exercise pressure North Korea so that it comes forward and engages in this serious dialogue".
Pence declined to comment when asked if the USA used cyberattacks to thwart the North's latest missile launches.
The term "reckless" is one the North Koreans have used to describe continuing large-scale US and South Korean military exercises, which the North calls a dress rehearsal for an invasion.
Pence also said the US would protect freedom of navigation in the South China Sea, the sea lanes vital to global shipping where China has been staking claim to disputed territory.
He did not comment on what might have caused the missile to fail but a n official said the missile was a Scud variant that the U.S. calls a KN-17.
While Pence brought up the issue of reforming the five-year-old bilateral trade pact with South Korea in his previous stop, the vice president emphasized in Japan that Trump aims at reforming the tax code in the U.S.in order to boost businesses for both Washington and Tokyo.
Speaking to USA and Japanese troops on board the USS Ronald Reagan aircraft carrier Wednesday, he called North Korea the most urgent and unsafe threat to the peace and security of the Asia-Pacific region.
Beijing, of course, has made this promise before, and experts warn there is no particular reason why China would honour it now - but the White House seems to have few better options.
She told reporters Wednesday: "The ball is in their court".
Chinese Foreign Ministry spokesman Lu Kang said all parties should make efforts to resolve the situation.
While many details about North Korea's nuclear missile technology are likely not publically available, Mann may have likely been referring to the often-cited North Korea's Taepodong 2 long-range missile.
