Others, however, have questioned whether a strong response from China - and China joining North Korea's adversaries - could lead to the conclusion desired by the USA and the UN. "Tensions are ratcheting up", as media reports often say, as Donald Trump and Kim Jong-un exchange verbal fires about decimating the other.
Ahead of his address at the United Nation General Assembly, Ri Yong-ho said in New York, "It could be the most powerful detonation of an Hydrogen-bomb in the Pacific".
Ri reportedly added that "We have no idea about what actions could be taken as it will be ordered by leader Kim Jong Un". The North claimed that it successfully tested a hydrogen bomb that can be placed on an intercontinental ballistic missile.
"We are clear that North Korea's actions are provocative and destabilising and our focus is on increasing the pressure on them to change course".
Trump said North Korea's textiles, fishing, information technology, and manufacturing industries were among those the United States could target.
North Korea has previously embraced racist, sexist and just plain rude statements about its enemies.
Trump said the measures are meant to disrupt critical North Korean shipping and trade networks by targeting any entity that does business with the nation.
China said on Saturday it will ban exports of some petroleum products to North Korea, as well as imports of textiles from the isolated North, in line with a United Nations Security Council resolution passed after Pyongyang's latest nuclear test.
"As long as North Korea continues its provocations, South Korea will keep considering various actions in cooperation with the U.S.to intensify global pressure on North Korea", the foreign ministry said.
Each Trump threat plays into this narrative.
He said Trump's remarks "have convinced me, rather than frightening or stopping me, that the path I chose is correct and that it is the one I have to follow to the last".
"I am now thinking hard about what response he could have expected when he allowed such eccentric words to trip off his tongue", Kim said.
"At present, management of North Korea-related business has become an issue of national-level politics and national security", according to the document seen by the sources.
Trump has returned to rhetoric he'd used during the campaign when he called Kim a "madman playing around with nukes" and a "total nut job".
