US seeks to freeze Nork leaders assets

BBC:

The US has proposed a range of new United Nations sanctions against North Korea, including an oil ban and a freeze on leader Kim Jong-un's assets.

The draft resolution circulated to the Security Council members comes after North Korea's sixth nuclear test and repeated missile launches.

Pyongyang also claims to have developed a hydrogen bomb and continues to threaten to strike the US.

China and Russia are both expected to oppose further sanctions.

The draft US proposal calls for a total ban on supplying a range of oil products to North Korea and a ban on its textile export industry.

It also suggests freezing the assets of Mr Kim and the North Korean government, as well as banning him and other senior officials from travelling.

North Korean labourers would also be banned from working abroad, principally in Russia's Far East and China.

Remittances from foreign earnings and textile exports are two of the most important remaining sources of income for North Korea.

It is not clear why China and Russia insist on a dialog with the North Koreans.  It has already been demonstrated by the very fact that they have a nuclear program that their word is no good.  They are not a viable negotiating partner and it is foolish to reward their bad faith by throwing money at them.
