A US special envoy said on Friday the United States was ready to hold constructive talks with North Korea to follow through on a denuclearisation agreement reached by the two countries last year, South Korea's foreign ministry said.
Stephen Biegun told his South Korean counterpart, Lee Do-hoon, that Washington wanted to make "simultaneous, parallel" progress on the agreement reached at a summit between President Donald Trump and North Korean leader Kim Jong Un in Singapore last year, the ministry said in a statement.
Both sides agreed to establish new relations and work towards denuclearisation of the Korean peninsula.
