Washington: Finding ways to convince North Korea to give up its nuclear ambitions will likely top the agenda at US President George W. Bush's weekend talks with South Korea's president after a fight over US beef exports was resolved.

Lee Myung-bak is the first South Korean president honoured with an invitation to Camp David, the US presidential retreat in Maryland's Catoctin Mountains, and Bush is likely to welcome his tougher stance on North Korea's atomic program.

North Korea failed to meet a December 31 deadline to reveal the extent of its nuclear weapons program and whether it provided nuclear technology to other countries, a key concern of the United States.

If Pyongyang finally makes the declaration, the United States is expected to ease sanctions imposed under the US state sponsors of terrorism list and the US Trading With the Enemy Act.
