North Korea blasted the United Nations on Friday for ignoring its repeated calls to hold an international forum to address the legality of the sanctions resolutions so far imposed on it.

"We are totally disappointed at (the) non ability of the secretariat that could not even make (a) decision of the issue organizing the international forum of legal experts," said North Korea's Deputy Ambassador Kim In Ryong at a press conference.

He was referring to the idea -- originally put forward in January -- to have a symposium either in New York or Switzerland. North Korea, officially known as the Democratic People's Republic of Korea, has been pressing for such a gathering to address what it considers to be an unfair practice, which it says is skewed to U.S. interests.

"The U.N. Secretariat should fulfill its responsibility before the international community by positively responding to our proposal" to clarify the legal basis for the imposition of the sanctions resolutions, he added.

Since 2006 after the North detonated its first underground nuclear test, it has been subject to six rounds of sanctions resolutions. Under those resolutions it is banned from carrying out such tests and from launching ballistic missiles, which it has done with greater frequency despite international pressure not to do so.

Increasingly, financial restrictions have become more biting over the years in efforts to restrict money flows that are used to fund the banned activities.

The envoy also claimed to have put the suggestion forward on 20 occasions. In addition to letters, addressed to U.N. Secretary General Antonio Guterres, for example, the North Korean mission has released numerous press statements and held multiple press conferences to promote the idea.

"I do not agree with the idea that the United Nations listens only to one or some of its member states," said Guterres' deputy spokesman, Farhan Haq, at a press conference when questioned about the claim. "The United Nations is a venue where we try to listen and embody the views of all 193 member states as best as we can."

He noted the international body had "continued to urge dialogue concerning the situation on the Korean Peninsula." Haq also stressed how the United Nations wants to see the North "comply with the relevant Security Council resolutions, to work with the international community, including with the International Atomic Energy Agency, and we are hoping for resumption of the sort of dialogue that we have seen concerning the Korean Peninsula some years back."

The six-party talks are the multiparty forum that is comprised of negotiators from both Koreas, the United States, Japan, China and Russia, who held talks to denuclearize the peninsula.

Those talks have been at a deadlock for years, although China, which is Pyongyang's closest ally, stands behind the value of diplomatic discussions.

Amid the spate of recent ballistic missile launches, the Security Council has held two emergency meetings within the span of a week to "strongly condemn" the moves, with Pyongyang flatly rejecting the censure.
