SEOUL/WASHINGTON -- U.S. trust in North Korea's professed commitment to denuclearization is being challenged as reports emerge that Pyongyang continues to build up production and research facilities and plans to conceal the full extent of its arsenal.

Sung Kim, the U.S. ambassador to the Philippines and a former envoy to South Korea, met Sunday with North Korean Vice Foreign Minister Choe Son Hui at the border village of Panmunjom in the demilitarized zone that divides the Korean Peninsula. This marked the first meeting of officials from the two countries since the June 12 summit between U.S. President Donald Trump and North Korean leader Kim Jong Un.
