It has been a long, frustrating wait for South Korean President Kim Dae-jung and his policy of engagement with North Korea.
For the first time since the inauguration of US President George W. Bush's administration 18 months ago, Washington is sending a team of senior officials to Pyongyang to see if North Korea is serious about ending its state of isolation.
The talks will cover a host of sensitive issues such as nuclear inspection and halting missile exports to rogue nations.
An eight-member delegation led by James Kelly, the assistant secretary of state for East Asian and Pacific affairs, is due to arrive in Pyongyang this morning.
It is a mission designed to see if the South Korean president has been right in pushing a policy of engagement with the North over the past four years, and if so, whether the US should follow the lead of Japan to induce the North to open up and reform economically.
Mr Kelly hopes to tackle five major topics: United Nations inspection of suspect nuclear facilities, missile development and exports, the need to pull back the North's conventional arms deployment from the demilitarised zone, inspection of biological and chemical weapons depots and human rights abuses.
