After the missile launch on Sunday, the United States, Japan and South Korea called a UN Security Council meeting to press North Korea to change course and dismantle its missile and nuclear programmes.
Haley was asked about comments by Russian President Vladimir Putin in Beijing on Monday who called North Korea's nuclear and missile tests "unacceptable" but also said the United States should stop intimidating Pyongyang.
The U.N. Security Council first imposed sanctions on North Korea in 2006 and has strengthened the measures in response to its five nuclear tests and two long-range rocket launches. "The Unification Ministry has considered options on this internally but nothing has been decided yet", Mr Lee said.
At the Pentagon, U.S. Defense Secretary Jim Mattis said that the recent missile test showed North Korea isn't complying with pressure from the worldwide community.

North Korea's deputy United Nations envoy said on Friday that the country will continue to strengthen its nuclear program as a necessary measure needed to counter US aggression.
They were believed to have held talks on prospects for containing North Korea's missile and nuclear weapons activities as well as the economic fallout over the deployment in South Korea of the USA missile defense system called THAAD.
He said Trump was also interested in achieving peace through dialogue with the North, although calling on sanctions for now to pressure Pyongyang.
Kim accused the council of playing "to the tune of the US again" and protested the Trump administration's demand for countries to choose allegiance between the United States and the Democratic People's Republic of Korea, his country's official name.
