"Once in effect, US passports will be invalid for travel to, through and in North Korea, and individuals will be required to obtain a passport with a special validation in order to travel to or within North Korea", State Department Spokeswoman Heather Nauert said in a statement last month announcing the policy.
"An additional Security Council resolution that does not significantly increase the international pressure on North Korea is of no value", she said in a statement Sunday.
The US Air Force has successfully tested an intercontinental ballistic missile at Vandenberg Air Force Base in California.
These restrictions apply for one year and may be renewed.
She has repeatedly stressed that the United States wants to ensure that a new resolution is "a strong resolution".
"We would like to sit and have a dialogue with them", Tillerson said. "I believe that the United States military, in combination with the South Korean military, would utterly destroy the North Korean military, but that would be done at high cost in terms of human life - in terms of infrastructure".
Haley said the time for talking is over and "China must decide whether it is finally willing to take this vital step".
Earlier in the day, a top Democratic Senator urged Trump to block China deals over North Korea.
North Korea's submarine fleet is believed to encompass about 70 subs, though the majority are quite old and likely cannot fire missiles.
Tillerson's remarks came after US President Donald Trump recently said China's efforts to rein in North Korea had "not worked" out even as he appreciated Beijing for its attempts to pursue its closest ally to abandon its nuclear ambitions.
North Korea called his death a "mystery".
Many soldiers are used as a labor force to compensate for the ineffective North Korean economy, so the army is not only about military organization.
He tried to refute arguments that the Trump administration was taking a protectionist stance, saying that both China and Europe were more protectionist because they subsidized export industries and had "formidable tariff and non-tariff trade barriers against imports". We do not seek a collapse of the regime.
Hundreds flee each year to China and make it to Thailand after an overland journey, from where they are usually sent on to South Korea.
The Moon administration apparently has no plan to budge on the issue while it continues to expand security cooperation with the United States.
