Clinton said the measures were designed to stamp out illegal money-making ventures used to fund the nuclear programme."These measures are not directed at the people of North Korea, who have suffered too long due to the misguided priorities of their government,'' Clinton said after talks with defence and military officials in South Korea on Wednesday.
"They are directed at the destabilising, illicit, and provocative policies pursued by that government,'' she said.She said the sanctions would be aimed at the sale or procurement of arms and related goods as well as the procurement of luxury items.
The US will freeze assets as well as prevent some businesses and individuals from travelling abroad, and collaborate with banks to stop illegal financial transactions, Clinton said.
Clinton arrived in Seoul, the South Korean capital, on Wednesday, with tensions between the North and South running high following the recent sinking of a South Korean warship, which left 46 sailors dead.
