South Korean media has reported that Pyongyang has invited top envoys of US President Barack Obama to visit the country for what would be the first nuclear negotiations between the two countries under his presidency.
The Democratic People's Republic of Korea (DPRK) recently offered the invitation to Stephen Bosworth, special envoy to the republic, and chief South Korean nuclear negotiator Sung Kim, according to the JoongAng Ilbo daily.
The report cited "an unidentified high-level diplomatic source in Washington" as saying that the US government is "strongly considering" sending them to the DPRK next month.
The US embassy in Seoul refused to comment on the story.
Elsewhere, South Korea have launched its first rocket but space officials said that the satellite it was carrying had failed to enter its intended orbit.
A Science Ministry statement called the launch a "partial success," as the satellite separated from the rocket normally before entering a different orbit.
The UN intensified financial sanctions against the DPRK after it conducted a similar launch on April 5.
