Mogherini said that as it always has, the European Union will immediately implement the new United Nations resolution, and work with other partners in the world to make sure everyone fully implements the economic sanctions.
USA ambassador Nikki Haley said Monday at the United Nations the tough new measures were a message to Pyongyang that "the world will never accept a nuclear-armed North Korea".
"The adoption of another illegal and evil ´resolution on sanctions´ piloted by the US served as an occasion for the DPRK to verify that the road it chose to go down was absolutely right", the North´s foreign ministry said in a statement published by the official KCNA news agency.
China and Russian Federation backed the move to impose a ban on textile exports and restrict shipments of oil products to North Korea.
Further, it also bans new visas for North Korean overseas workers, which the USA estimates would eventually cut off $500 million of tax revenue per year.
That would amount to a 10 percent cut in oil products, according to the US Energy Information Administration, which estimates annual exports to North Korea at almost 2.2 million barrels.
On Monday, Haley said the United States was not looking for war with North Korea and that Pyongyang had "not yet passed the point of no return".
Lawmakers who spoke Tuesday supported the U.S. pressure tactics, while voicing skepticism that North Korea could be forced into abandon nuclear weapons it regards as a guarantee of survival for the Kim dynasty.
This represents a reduction of 10 % of the petroleum products, according to the u. s. department of Energy, which is estimated at 2.2 million barrels, imports north Korean.
A foreign affairs committee in the US Congress' lower chamber is pushing to impose unilateral sanctions against major Chinese banks with a large US presence to force them to cut off alleged financial support for North Korea's nuclear and missile programme. The resolution also freezes the assets of the North Korean regime and forbids joint ventures with the North Korean government.
The UN Security Council has adopted a resolution tightening sanctions on North Korea in response to the country's sixth nuclear test.
The US needs to switch from isolation to communication in order to end an endless loop on the Korean peninsula, where nuclear and missile tests trigger tougher sanctions and tougher sanctions invite further tests.
Security Council officials said American and Chinese diplomats were still working out the text as of late Sunday, the Associated Press reported.
Dr Cheong Seong Chang of the Sejong Institute think-tank said the move will not have a huge impact on the North's military as crude oil supply remains the same.
But after the latest nuclear test, Haley took a more public approach, announcing that she would circulate a draft resolution to all council members and that she meant to call for a vote on September 11.
"No matter how the U.S. and its puppets kick up a ruckus, our republic, which has a strong military and the most powerful Juche bombs and weapons, and whose territory has all turned into fortresses, and all its people armed to the teeth, will remain an eternal iron-clad citadel", it said.
