North Korea threatens to boost nuclear arsenal | Reuters.com

Reuters.com: "TOKYO (Reuters) - North Korea said on Thursday it might boost its nuclear deterrent if six-country talks on ending its atomic programs remained deadlocked, but said it would return if Washington met a demand to unfreeze it assets.

Pyongyang's top envoy to the stalled negotiations told a news conference in Tokyo the United States must lift what the North considers to be financial sanctions against it.

'I told them the minute we have the funds or I have the funds in my hand I will be at the talks. But if they continue to come with pressure and sanctions, we will respond with extremely strong measures,' envoy Kim Kye-gwan said."
