"We stand alongside our global partners in making clear that North Korea must adhere to United Nations resolutions created to secure peace and stability in the region and stop its pursuit of nuclear weapons", he said.
Sunday's launch was carried out around dawn from Sinpo, a site on North Korea's east coast where it has a shipyard.
The Obama administration sanctioned such saboteur efforts in 2014 when the White House asked Pentagon officials to conduct cyber strikes against the North Korea's test missile launches.
South Korea said the North's combined show of force "threatened the whole world" but a USA foreign policy adviser travelling with Pence on Air Force Two appeared to defuse some of the tension, saying the test of what was believed to be a medium-range missile had come as no surprise.
The failed launch from North Korea's east coast, ignoring repeated admonitions from major ally China, came a day after North Korea held a grand military parade in its capital, marking the birth anniversary of the state founder, displaying what appeared to be new long-range ballistic missiles. As the brown bomber jacket-clad vice president was briefed near the military demarcation line, two North Korean soldiers watched from a short distance away, one taking multiple photographs of the American visitor.
As concern about the situation mounted, The Sunday Times reported that President Trump's military advisers have assured the United Kingdom that America has the capability to neutralise North Korea's nuclear programme using conventional weapons. But Pence expressed impatience with the unwillingness of the regime to move toward ridding itself of nuclear weapons and ballistic missiles.
"The missile blew up nearly immediately", Benham said.
A South Korean defense official said the action took place in Sinpo, a port city in eastern North Korea. South Korea's Defense Ministry said it was analyzing exactly how the North Korean launch failed.More news: Wilson scores in OT as Caps survive scare to beat Leafs
The group said the leaflets contained all the details of the assassination of Kim Jong-nam which occurred at Malaysia's Kuala Lumpur International Airport on February 13, as well as criticism of the Pyongyang regime.
That same secrecy is responsible for what USA officials have consistently described as limited US intelligence about the North Korean government's inner workings. But at the same time, McMaster said on "This Week" on ABC that "it's time for us to undertake all actions we can, short of a military option, to try to resolve this peacefully".
"Why would I call China a currency manipulator when they are working with us on the North Korean problem?"
The official said Trump had numerous ways to respond if needed. Trump tweeted on Sunday.
North Korea has conducted five nuclear tests, including two previous year.
Along with the deployment of the USA aircraft carrier and other vessels into waters off the Korean Peninsula, thousands of US and South Korean troops, tanks and other weaponry were deployed last month in their biggest joint military exercises. That led North Korea to issue routine threats of attacks on its rivals if they show signs of aggression. North Korea also showed what is believed to be a KN-14 missile on a transporter erector launcher (TEL).
The agency was founded in 1993 by two British citizens living in China, Nick Bonner and Josh Green, and claims its takes more than 2,000 people to North Korea each year.
Worry about North Korea has also strained ties between China and South Korea because China objects to the deployment of a U.S. Terminal High Altitude Area Defense (THAAD) anti-missile system in the South.
