In response, on 14 October, the UN Security Council adopted Resolution 1718, which called on North Korea not to conduct further nuclear or missile tests, abandon its weapons of mass destruction and missile programmes, and immediately participate in the six-party talks. Difficulties in reaching a review system delayed the second measure until 11 October 2008. The need for an audit system was confirmed in a joint statement from the six parties on July 12. A Proposal by the United States of August 11, 2008 to authorize inspections at sites throughout North Korea was strongly rejected. North Korea stressed the need to limit inspections at Yongbyon and announced that it would cancel the disability measures and announced that it would restore its reprocessing plant. After Von Hill`s visit to Pyongyang in early October, a verbal agreement was reached. The agreement allowed inspections outside Yongbyon when China, Japan, Russia, South Korea and the United States agreed. After the end of the first meeting, the climate of the negotiations deteriorated markedly. U.S. sanctions against North Korean business units and Delta Asia Bank in Macau have strongly condemned Pyongyang. North Korea again boycotted the six-party talks and conducted several missile tests in July and the first nuclear test on October 9, 2006.
In response to the deadlock in the six-party talks on the issue of the review, Washington attempted to end energy aid to North Korea in exchange for the invalidity of its Yongbyon nuclear facility. U.S. State Department spokesman Sean McCormack said at a December 12 news conference that the delivery of heavy oil as part of this aid would not continue without an audit agreement and said that “there is an agreement between the parties… that oil supplies will not progress without progress. On May 25, 2009, North Korea detonated a nuclear device at the bottom.  The test was condemned by the United Nations, of NATO, the other five members of the six-party talks and many other countries in the world. [Citation required] On 11 October 2011, South Korea appointed a new envoy for the six-party talks; Lim Sung-Nam, who worked upstream for the Ministry of Tourism and Sports. Since the last round of talks, each of the parties involved has called for a temporary resumption. In December 2010, China, Japan, South Korea and the United States called for an emergency meeting of the six-party talks.
In 2014, a North Korean special envoy informed Russian President Vladimir Putin that North Korea was ready to resume the six-party talks. China requested its resumption in August 2017. However, little progress has been made in recent times with regard to the continuation of the six-party talks. On November 23, 2010, North Korea fired on the South Korean island of Yeonpyeong. Two South Korean soldiers were killed and a dozen wounded after North Korea fired dozens of Gaddafi shells at a South Korean island that set fire to more than 60 homes and sent civilians on the run. Both incidents obstructed the six-party talks during this period.  In early August 2003, North Korea declared its readiness to participate in six-party talks in Beijing. Between the impasse and the crisis, the six-party talks made critical strides in 2005, when North Korea pledged to abandon “all existing nuclear weapons and programs” and return to the Non-Proliferation Treaty, and in 2007, when the parties agreed on a number of measures to implement the 2005 agreement. While the measures have never been fully implemented and North Korea remains outside the non-proliferation program, Pyongyang has disabled the nuclear reactor that produced plutonium for its weapons program. Although the six-way agreements lead to the verifiable denuclearization of the Korean Peninsula, existing agreements did not require the conclusion of a review protocol.
