A top U.S. diplomat says he is "absolutely certain" complete denuclearization of North Korea is in reach.
U.S. Special Representative for North Korea Stephen Biegun met with his South Korean counterpart in Seoul Monday in a show of unification.
Biegun says the two countries have a shared goal of bringing "an end to 70 years of war and hostilities on the Korean Peninsula."
The meeting comes on the heels of South Korea making some major moves to develop inter-Korean relations with the North.
In recent weeks, the two countries agreed to remove some guard posts from their shared border, remove all weapons and ammunition from the border village of Panmunjom and reconnect their railways and roads.
Biegun says the U.S. and Seoul will "need to meet up as often as possible to make sure there is no daylight whatsoever between our two allies."
North Korea has taken some steps toward denuclearization. In May, the country said it destroyed parts of its nuclear test site. It's unclear if the site was fully dismantled, but earlier this month North Korean leader Kim Jong-un agreed to allow experts into the site to inspect it.
President Donald Trump has agreed to a second meeting with Kim. That meeting is expected to take place after the U.S. midterm elections on Nov. 6.
