Meanwhile this information emerged around the same time the U.S. military flew two strategic bombers over the Korean peninsula in a show of force late on Tuesday.
The North Korean authorities were reported to have told one of the delegates that they were preparing the next test launch with a new intercontinental ballistic missile capable of reaching the west coast of the US.
Pyongyang conducted its fifth nuclear test on the anniversary of the founding day of North Korea past year.
Those are the findings of a poll by the Associated Press-NORC Center for Public Affairs Research, as tensions between the adversaries escalate and North Korea comes closer to its goal of having a nuclear-tipped missile that could strike the continental United States.
At the end of last month, North Korea's foreign minister Ri Yong-ho said that the USA had "declared war" on the authoritarian state and was "right" to shoot down American planes.
President Donald Trump on Wednesday appeared to confirm he had North Korea in mind last week when he described a gathering of military leaders as "the calm before the storm".
"North Korean actions are illegal, in defiance of United Nations Security Council resolutions and Australia will play our part in supporting South Korea and allies in deterring North Korea from further provocative acts and compelling it to return to the negotiating table", Bishop noted.
Ri has previously called Trump "President Evil" and his comments are likely to fuel an escalating war of words between the USA president and North Korean leader Kim Jong Un.
In his latest tweet over the weekend, Trump reiterated that diplomatic efforts with North Korea have consistently failed, adding that "only one thing will work".
The two B-1B bombers were accompanied by two F-15K fighters from the South Korean military after leaving their base in Guam, the South's Joint Chiefs of Staff said in a news release.
The EU also said a total number of 63 individuals and 53 entities were sanctioned under restrictive measures as listed by the United Nations, while 38 individuals and four entities have been designated by the bloc autonomously.
Two supersonic USA bombers have flown over the Korean peninsula in a "show of force" despite Kim Jong-Un's threats to shoot them down. There were even concerns that North Korea prepped hundreds of computers for a massive attack on its southern neighbor. A similar number, or 69 percent, said they are concerned about the threat to U.S. allies, such as South Korea and Japan.
"The current situation - when the USA resorts to maximum pressure and sanctions, to outrageous military threats against the DPRK - is not at all an atmosphere to negotiate", Ri said, according to TASS.
