US Ambassador to the United Nations Nikki Haley is "done talking about North Korea" after the rogue nuclear state launched its second intercontinental ballistic missile on Friday.

On Sunday, Haley tweeted that she is "done talking about North Korea. China is aware they must act. Japan and South Korea must increase pressure. Not only a US problem. It will require an international solution."

However, she also questioned the use of a UN Security Council resolution, saying any solution "that does not significantly increase the international pressure on North Korea is of no value."

"North Korea is already subject to numerous Security Council resolutions that they violate with impunity.

"China must decide whether it is finally willing to take this vital step. The time for talk is over."

"The danger the North Korean regime poses to international peace is now clear to all."

According to Haley, options for sanctions include restricting oil shipments to North Korea's weapons and military programs, imposing sanctions on senior officials, and increasing air and maritime restrictions.

As of yet, no one has asked the UN Security Council to hold a meeting over North Korea.

Meanwhile, the James Martin Center for Non-proliferation Studies' Shea Cotton on Saturday told AM, "Our estimates from the first one had the missile going about 6,700 kilometers, which put Alaska within range.

"Our estimates with this one are that if it was fired within full range....this would go about 10,000 to 11,000 kilometers and at that point they've basically put all of the United States within range."

These estimates provide the maximum range. Range may vary depending on payload.
