Adding it is not the preferred option, he urged all nations to do more to rein in the North, which he called "one of the world's most urgent and unsafe security problems".
"If North Korea continues to walk down this path, it has no bright future. And at that point there is not a whole lot the security council is going to be able to do from here when you have cut 90% of the trade and 30% of the oil", she said.
US President Donald Trump will hold a series of meetings with world leaders on the sidelines of the UN General Assembly meeting next week in NY, the White House said on Friday.
On the other hand, the US and South Korea have announced diminishing willingness to talk to North Korea as it continues its provocative missile launches and nuclear tests.
North Korea launched what appeared to be an intermediate-range ballistic missile over northern Japan early Friday (local time), defying worldwide calls to halt its provocations.
President Donald Trump has derided the U.N for its "utter weakness and incompetence" and even pledged to cut US taxpayer funding that contributes to its budget.
"We try and push through as many diplomatic options as we have", Haley said.
South Korean President Moon Jae-in also convened a National Security Council meeting to monitor the situation and prepare for any emerging threats from North Korea. The North Koreans must have been confident that their latest test - an audacious advance by some 1,000km on their earlier (29 August) overflight of Japan - would be successful and that the risk of the missile breaking up over Japanese airspace was minimal. That plan seeks to set the stage for a resumption of talks after Pyongyang suspends its nuclear and ballistic missile activity and the US and South Korea suspend their joint military exercises.
"The South Korean government said they fired a missile within minutes afterwards, from their coastline".
North Korea fired a ballistic missile over the northern Japanese island of Hokkaido Friday, the latest in a stream of missile tests that have looked to defy the worldwide community. Equally, as the North moves closer to placing a miniaturised nuclear warhead on a missile capable of hitting a United States city with pinpoint accuracy, how great is the risk that the U.S. might feel compelled to preemptively attack the North to prevent Kim from threatening the USA with a nuclear attack?
"We call on all nations to take new measures against the Kim [Jong Un] regime", the top USA diplomat said. "China and Russian Federation must indicate their intolerance for these reckless missile launches by taking direct actions of their own", Tillerson said. "So, having said that, I have no problem with kicking it to (Defense Secretary James) Mattis because I think he has plenty of options". A trio of missile launches and a hydrogen bomb test that is the communist nation's most powerful to date.
Ultimately, the U.S. needs to not only deter North Korea, but also to reassure Japan and South Korea that they will neither be abandoned by their ally nor entrapped in a wider conflict precipitated by America's own independent strategic decisions.
