The United States has deployed a naval strike group to the area led by the carrier USS Carl Vinson, which on Saturday began drilling with the South Korean navy to practice procedures for tracking and intercepting enemy ballistic missiles.
North Korea's state media has reiterated the country's goal of developing a nuclear missile capable of reaching the US.
"Failing to act now on the most pressing security issue in the world may bring catastrophic consequences.
During the (presidency of Donald) Trump North Korea has fired missiles nine times already", Denisov said.
US President Donald Trump did not answer reporters' questions about the launch, but he did tweet.
But he said the United States can not allow North Korea to have a better nuclear arsenal. "And I will tell you, a man that I've gotten to like and respect - the president of China, President Xi - I believe has been putting pressure on him also", Trump said in the interview. Sources had said back then that the missile "blew up nearly immediately" after launch. But he spelled out no further punitive steps his government might consider, despite Tillerson's assertions in an interview hours ahead of the council meeting that Beijing would impose sanctions of its own if North Korea conducts another nuclear test.
Tillerson repeated a recent flurry of US warnings that the Trump administration is prepared to use military force, if necessary, to constrain North Korea from developing a nuclear threat.
Trump raised eyebrows in South Korea last week when he said would make Seoul pay $1 billion for the missile defense system. It said the launch was a clear violation of United Nations resolutions and warned the North not to act rashly.
China, Pyongyang's number one trade partner, has repeatedly called for a return to talks on denuclearization but has been reluctant to use economic pressure that could destabilize North Korea.
Advocaat returns as Dutch boss for third time
Dick Advocaat has been appointed as the Netherlands manager for the third time, it was confirmed on Tuesday. One is Henk ten Cate with Fred Rutten as assistant or Dick Advocaat with Ruud Gullit as assistant".
It had been feared that North Korea could conduct another nuclear test earlier this week to commemorate the founding of the nation's military.
That means, Lt. Gen. McMaster said, working to enforce current United Nations sanctions and perhaps ratcheting them up.
Positions of Russian Federation and China on the North Korean nuclear issue almost coincide, Denisov said.
On Saturday, a North Korean mid-range ballistic missile broke up a few minutes after launch, the third test-fire flop this month.
"I don't know", Trump replies.
"Something that's ready to go could be taken from the larger package and expedited".
The UN Security Council, which traditionally condemns all missile launches by Pyongyang, is likely to start discussing a statement to condemn the missile launch, said diplomats.
The standoff over North Korea's determined push to expand its nuclear arsenal and to develop more powerful missiles has sparked tensions since the mid-1990s, and previous diplomatic efforts under Presidents Clinton, Bush and Obama all ultimately failed.
