Pence insisted the Trump administration would handle North Korea differently than past administrations, including encouraging more involvement from China.
"We've seen China begin to take some actions to bring pressure on North Korea, but there needs to be more," Pence told CNN. He argued that past administrations' tactics had failed and the U.S. would "redouble" efforts to bring about a diplomatic solution.
Pence also expressed support for South Korea.
Pence reportedly went outside of the protected Freedom House at the DMZ, prompting North Korean soldiers to pull out cameras and take pictures, CNN reported.
