Vice President Mike Pence, who called the latest missile test a "provocation", is now in South Korea to meet with US and South Korean military.

"It's time for us to undertake all actions we can, short of a military option, to try to resolve this peacefully", he said on ABC's "This Week" programme.
Hours after North Korea paraded its weaponry and attempted a missile launch, Trump's national security adviser said the president will not allow Kim Jong Un's regime to threaten the U.S.
Yet Boris Johnson spoke up in support of the U.S.'s activity in the region saying, "We stand alongside our worldwide 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".
Russian Federation has warned the United States against any "unilateral action" against North Korea, saying any response to Pyongyang's nuclear activities should not violate "international law", amid reports of potential military confrontation between North Korea and the US. Trump and his advisers have pointed to Beijing's move to restrict coal imports from North Korea as a sign Beijing is listening, and the USA says China has turned back some shipments in recent days.
"The KPA will deal deadly blows without prior warning any time as long as the operation means and troops of the USA and South Korean puppet forces involved in the "special operation" and "preemptive attack" targeting the [Democratic Republic of Korea] remain deployed in and around South Korea", the North Korean military warned in late March.
Pence said President Donald Trump are hopeful that China will now use its "extraordinary levers" to pressure the North to abandon its nuclear and ballistic program. "I have great confidence that China will properly deal with North Korea".
At today's White House press briefing, press secretary Sean Spicer said Trump won't be "drawing lines in the sand" when talking about possible actions against North Korea.
So why the recently escalation of tensions with North Korea?
Then, under the previous Conservative government, Canada adopted a "controlled engagement" policy with North Korea.
"North Korea would do well not to test his resolve - or the strength of the Armed Forces of the United States in this region", the vice president warned.
Over the weekend following the 105th birthday celebrations of the state's founder, Pyongyang tested what most experts believe was a medium range missile which exploded immediately after leaving the launch pad.
'We want to see North Korea abandon its reckless path of the development of nuclear weapons, and also its continual use and testing of ballistic missiles is unacceptable'.
On Tuesday, the Vice President travels to Tokyo where he's expected to hold more talks on the North Korea issue. Last week, he said he would not declare China a currency manipulator, pulling back from a campaign promise, as he looks for help from Beijing, which is the North's dominant trade partner.
In February China announced it was halting all imports of coal from North Korea - a crucial earner for Pyongyang - for the rest of the year. US and South Korean defense officials are trying to determine what type of missile was used.
