Pence also told gathered servicemembers from both USA and Japanese forces that Tokyo will "assume a larger role and responsibility" within its security alliance with Washington.
"We're already seeing our allies in South Korea and Japan and the wider world standing behind us, but China is taking unprecedented steps to economically isolate North Korea and given the fact that China represents more than 80% of the exports from North Korea is enormously important", Pence said.
"The leader of North Korea again recklessly tried to provoke something by launching a missile", U.S. Defense Secretary Jim Mattis said on April 18, adding that the United States was "working closely" with China to engage Pyongyang.

The unannounced visit Monday at the start of his 10-day trip to Asia was a U.S. show of force that allowed the vice president to gaze at North Korean soldiers from afar and stare directly across a border marked by razor wire.
He said that under Trump, the USA will stand up to its enemies with its allies.
"We're reviewing all of our trade agreements across the world to ensure that they benefit our economy as much as they benefit our trading partners", Pence told the American Chamber of Commerce in Korea.
Pence told reporters near the DMZ that President Donald Trump was hopeful China would use its "extraordinary levers" to pressure the North to abandon its weapons programme, a day after the North's failed missile test launch.
