US President Barack Obama has warned North Korea that it will "achieve nothing by threats or by provocations".
The warning comes as Pyongyang prepares to launch a long-range missile which it says will put a satellite in orbit.
Mr Obama was speaking after talks in Seoul with South Korean President Lee Myung-bak, ahead of global summit on nuclear security.
