Foreign Minister Julie Bishop has used her address to the United Nations General Assembly to warn that the international order faced increasing threats, chiefly from North Korea and terrorism.

Ms Bishop praised the work the UN had achieved since World War II but said that was under threat, particularly from North Korea.

“The regime of Kim Jong-un is openly defying the United Nations Security Council [UNSC],” she said.

“Its illegal nuclear and missile programs violate multiple UNSC resolutions.

“The security of millions of people is at risk as a result of North Korea’s refusal to abide by international laws and norms.”

The Foreign Minister said North Korea’s continued aggressive and defiant push for nuclear arms was flouting the authority of the UN Security Council.

On Thursday (local time), North Korea threatened it may test a hydrogen bomb in the pacific.

“North Korea is the only state that is currently testing nuclear weapons and is the only state to do so this century,” Ms Bishop said.

She told the assembly international order and stability was also under threat from terrorism and that Australia was among the nations to suffer attacks.

Ms Bishop called on the world to act collectively to stamp them out.

“Global terrorism and extreme Islamist ideologies driving it must be confronted and defeated,” she said.

Bishop backs Paris Climate Accord

Ms Bishop also broke with ally the United States and heartily endorsed the Paris Climate Accord which President Donald Trump has pledged to leave.

“Australia is a strong supporter of the Paris agreement, and here at the United Nations we have voiced our support specifically on risk mitigation for coral reefs, which are among the most valuable environments on our planet,” she said.

“They support more biodiversity than almost any other ecosystem, they’re vital to the worlds fisheries, protect our coastlines and generate significant tourism revenue.”

On Saturday (local time), North Korea is expected to address the General Assembly and a week of bombastic rhetoric could get even louder.

Russia’s foreign minister Sergei Lavrov called the insult trading with the US a kindergarten fight.

The spokesman for UN Secretary-General Antonio Gutteres called for the focus to be on diplomacy rather than rhetoric.

So far this week the former has triumphed over the latter.
