The North said it would take an unspecified "resolute action of justice" and would never place its nuclear program on the negotiating table or "flinch an inch" from its push to strengthen its nuclear deterrence as long as US hostility against North Korea persists.
Yet North Korean Foreign Minister Ri Yong-ho proclaimed at the conference on Monday that North Korea is a "responsible nuclear power and ICBM state", blaming the United States' "hostile policy" for its nuclear and missile development which would not be subject to negotiations.
Kono, in his turn, expressed hope that the countries would cooperate "in a broad range of areas" to build a new era of bilateral relations, the media added.
On the sidelines, the foreign minister met his counterparts including China, Russia, Indonesia, East Timor and the host country Philippines.
"We actually had very thorough talks", Wang said, adding "The Chinese side urged the North Korean side to calmly handle the resolutions the UN Security Council just made towards North Korea and to not do anything unbeneficial towards the worldwide community such as a nuclear test".
Nikki Haley, ambassador to the U.N. for the United States, which drafted the resolution, said the vote "put the North Korean dictator on notice" and represented a "strong, united step holding North Korea accountable for its behavior".
The U.S. -sponsored sanctions approved unanimously Saturday by the U.N. Security Council target already-meager North Korean exports such as coal, iron, lead and seafood, as well as revenue streams such as foreign joint ventures.More news: Sales of gold bars rising amid rising tension on peninsula
"And we hope, again, that this ultimately will result in North Korea coming to the conclusion to choose a different pathway, and when the conditions are right that we can sit and have a dialogue around the future of North Korea so that they feel secure and prosper economically". Nikki Haley, the USA ambassador to the United Nations, called the sanctions the most stringent on any country "in a generation".
Representing the United States at the dinner was Susan Thornton - acting assistant secretary of State for East Asia and Pacific Affairs. Aside from calling for more sanctions, Trump's approach has centered on enlisting China - the North's biggest trading partner - and others to lessen ties to Pyongyang. Trump had been stressing how China could play a large role in containing North Korea.
Asked about whether the latest round of sanctions against Pyongyang will have the desired effect, given North Korea's race toward nuclear development and the time it takes for sanctions to kick in, Tillerson said that "when do these actually have a practical bite on their revenues. the more important element of that is just the message that this sends to North Korea of how unacceptable the entire worldwide community finds what they're doing to be".
Wang also urged the USA and South Korea "to stop increasing tensions" and said that all sides should return to negotiations. Foreign Minister Wang Yi unleashed harsh words on sensitive topics against South and North Korea, the United States, and Japan. "They never have and likely never will". Beijing praised Tillerson for declaring the US wasn't seeking regime change in North Korea.
"China's strategy is to ensure the status-quo hold for at least the short- to medium- term", he said.
The U.S. also warned it planned to rigorously monitor China's compliance with the new penalties.
