The US earlier pressed for a full oil embargo on North Korea after it tested its most powerful nuclear bomb to date in September, but dropped that demand in negotiations on a sanctions resolution with China.
The isolationist state recently tested a new intercontinental ballistic missile that, it claimed, could reach anywhere on the U.S. mainland.
President Trump in a tweet Thursday morning said that North Korea's recent missile launch showed that the Chinese envoy who just returned from the country "seems to have had no impact on Little Rocket Man". "Russian Federation and China condemned the launch". US President Trump derided Kim Jong-un as a "sick puppy" and threatened "major" new sanctions after Pyongyang tested its third ICBM - which it claimed was capable of striking anywhere in the United States.
"We know the main driver of its nuclear production is oil", she said.
Trump's tweets further inflamed tensions reignited this week after North Korea said it had successfully tested a new intercontinental ballistic missile in a "breakthrough" that put the US mainland within range of its nuclear weapons whose warheads could withstand re-entry to the Earth's atmosphere.

As Paul Bracken, a professor of political science at Yale, told Business Insider, Trump has "been reasonably effective" in isolating North Korea and rallying support for sanctions internationally.

"We have never sought war with North Korea and still today we do not seek it". While Haley remarked that the "North Korean regime will be utterly destroyed" in such a war, she neglected to mention the damage that South Korea, and possibly the U.S., could also face from a North Korean nuclear attack.
Foreign Minister Kang Kyung-wha is planning to make her first visit to Japan as Seoul's top diplomat later this month to discuss cooperation on reining in North Korean military threats and ways to resolve the countries' historical feud, diplomatic sources said Friday. But China has refused to turn off its pipeline shipping crude to the North Beijing fears that taking tougher actions could cause the regime to collapse, triggering a refugee crisis across its border with the North and eliminating a strategic buffer separating China from the U.S. military in South Korea.
But Mike Elleman, a leading missile expert, wrote on 38 North, a website for North Korea analysis, that despite the missile's size it still probably couldn't send a heavy nuclear warhead as far as the US's east coast.
"We need China to do more", Ms Haley said on Wednesday.
