Kim Jong-un's personal assets are being targeted by the USA draft resolution.
The announcement came soon after the US Forces Korea transported four additional THAAD rocket launchers into its new base in Seongju, some 300 kilometers south of Seoul, despite fierce protests by local residents and activists.
"We must make North Korea immediately and fully comply with all relevant UN Security Council resolutions and abandon all its nuclear and ballistic missile programmes in a complete, verifiable and irreversible manner", Abe insisted.
It will likely prove to be at least 10 times stronger than anything the North tested before.
Mr Putin, who shared a platform with South Korean President Moon Jae-in and Japanese Prime Minister Shinzo Abe, warned it was "impossible to scare" Pyongyang.
The Russian leader Tuesday criticized sanctions as "useless and ineffective", instead urging the global community to offer security guarantees to North Korea.
"I have an executive order prepared".
Seoul had said that Pyongyang would follow the nuclear test with another missile launch over the weekend.
"The president will consider that at the appropriate time once he gives the United Nations time to act", Mnuchin told reporters.
Moon Jae-in approved the full deployment of the Thaad system this week in the wake of the detonation of the nuclear device on Sunday, drawing widespread condemnation and calls for stricter United Nations sanctions.
In the joint media session, Moon said he and Putin agreed that it is imperative to resolve the North Korean nuclear and missile crisis, calling it the most urgent and important challenge. Kang told parliament that her nation is working with the USA for the "strongest" measures against North Korea.
The tension escalated after Korea, on September 3, announced a successful test of a thermonuclear explosive that could be used as a warhead at an intercontinental ballistic missile.
In tweets earlier this week, Trump threatened to halt all trade with countries doing business with North Korea, a clear warning to China.
South Korean Prime Minister Lee Nak-yon said his country expects its northern neighbor to test-fire the type of long-range missile created to deliver a nuclear warhead to far-off places such as the United States on Saturday, an important North Korean holiday. As democratic countries, we have elections and changes of governments.
The launchers installed on Thursday were added to the two already set up on the site, an old golf course located about 300 km south of Seoul.
"Is it right to say that we want to be protected by USA nuclear weapons but we don't want them on our soil?" asked the former minister, while acknowledging it was an "emotional" issue in pacifist Japan, still scarred by the obliteration of Hiroshima and Nagasaki in World War II. North Korea now believes that its nuclear arsenal is its best deterrent against an American invasion, and hence will not give it up no matter how much the United States tries to push them.
Russian President Vladimir Putin again rejected US calls for new sanctions against North Korea after its sixth and most powerful nuclear test, echoing China's resistance to more punitive measures to pressure Pyongyang into abandoning its atomic and missile programs.
During his press conference with Kuwait's Amir al-Sabah, President Trump was asked about his administration's goals pertaining to the latest threats from North Korea.
