After weeks of negotiations, the UN sanctions committee is expected to give final approval to the new guidelines on Monday.

Once approved, a notice will be sent to the UN’s 193 member-states by the committee “to provide a clear explanation of its comprehensive humanitarian exemption mechanism” which will “improve the delivery of humanitarian assistance to DPRK,” according to the documents.

The move comes as the United States is calling for maximum pressure to be maintained against North Korea to compel Kim Jong-un to follow through on his pledge to denuclearise the Korean peninsula.

After Russia and China urged the council to ease sanctions, US Ambassador Nikki Haley said the United Nations should not do “one thing” until North Korea takes action to dismantle its nuclear and missile programmes.

A US official said the guidelines would ensure that “only critical, life-saving humanitarian activities needed in North Korea can continue” and that requests for exemptions will undergo a detailed review.

“The United States has been very clear that we will continue to enforce the current sanctions until we achieve the final, fully verified, denuclearisation of North Korea,” said the official, speaking on background.

Asked about the new guidelines, a Dutch official, speaking as the chair of the sanctions committee, said: “We want to make clear that this is about easing the process, not about easing the sanctions.”

The Security Council last year adopted three rafts of sanctions targeting North Korea’s economy in response to Pyongyang’s sixth nuclear test and a series of ballistic missile launches.

Those sanctions ban North Korea’s exports of raw commodities while severely restricting imports of a range of goods and supplies of oil – vital for the country’s military.

The measures have had a chilling effect, with UN agencies and aid organisations struggling to find partners willing to deal with the bureaucratic red tape from the tight sanctions regime on North Korea.

“Economic sanctions are not supposed to have an impact on impartial humanitarian action. But they do. They have unintended consequences,” said Simon Schorno, the head of aid operations for the International Red Cross in Asia.

“We haven’t seen the guidelines yet but we have been promised that they will speed up procedures, exemptions, and generally make processes run smoother. We’re hopeful that the guidelines will make carrying out our work easier.”

At a UN meeting last month, North Korean Deputy Ambassador Kim in Ryong complained that deliveries of medical equipment such as X-ray machines, anti-malaria insecticides and reproductive health kits had been held up for months.

Kim said humanitarian aid was being “politicised” and argued that denying assistance to North Koreans in need was a violation of human rights.

The United Nations is also facing a major funding shortfall for its aid operations in North Korea.

An appeal for US$111 million in funding for food, medicine and other basic needs for 6 million North Koreans has so far raised only US$12 million – 10.9 per cent of the total amount needed.

Only four countries have come forward with donations: Switzerland, Sweden, Canada and France.
