"It's not fair all the time just to press and push North Korea," Seif al-Islam Kadhafi, who holds no official position but is seen as a representative of his father, told a news conference in Tokyo.

"You have to give them political and economic incentives," said Kadhafi, whose country struck a deal with the United States and Britain in December 2003 not to dismantle its nuclear, chemical and biological warfare programs.

The United States accuses North Korea of operating a secret uranium-enrichment program in a standoff that erupted in 2002.

Little progress has been made since China, Japan, Russia, South Korea and the United States entered talks with North Korea in August 2003.

The isolated communist state has suspended talks over Washington's "hostile" attitude and sought promises that it will not invade.

Seif al-Islam Kadhafi met Monday with Japanese Prime Minister Junichiro Koizumi and Foreign Minister Nobutaka Machimura, whose government is also embroiled in a row with North Korea over its kidnappings of Japanese citizens.

Citing the Libyan experience, Kadhafi said the international community must offer "attractive" deals to North Korea to make it give up its weapons program.

"If you take Libya for an example, we made that decision according to promises and incentives from the United States and Britain, which made the initiative quite an attactive deal for Libya," he said.

"It's a package deal," he said, adding: "We have to guarantee (to North Korea) that there is no hidden agenda and there is no trap behind the whole game."

Following Libya's announcement, the United States lifted most sanctions against the country and there is now a permanent US diplomatic presence in Tripoli for the first time since the early 1980s.

But US sanctions related to Libya's alleged support for terrorist groups are still intact as the country remains designated as a "state sponsor of terrorism".

Kadhafi will Wednesday visit the World Exposition, a showcase of technology and innovation with exhibits from more than 120 countries in central Aichi prefecture, to promote the Libyan pavilion, which includes his own paintings.
