US President Donald Trump vowed on Thursday to confront North Korea "very strongly" after its latest missile test and urged other nations to show Pyongyang that there would be consequences for its weapons programme.
On Tuesday, North Korea launched an intercontinental ballistic missile that landed into waters east of the Korean Peninsula. Some experts believe that the missile has the range to reach Alaska and Hawaii and perhaps the US Pacific Northwest. North Korea said it could carry a large nuclear warhead.
Speaking at a news conference with Polish President Andrzej Duda, Trump said North Korea was "a threat, and we will confront it very strongly". He said that the US was considering "severe things" for North Korea, but that he would not draw a "red line" of the kind that his predecessor, Barack Obama, had drawn but not enforced on the use of chemical weapons in Syria.
Trump added: "They are behaving in a very, very dangerous manner and something will have to be done."
US Defence Secretary Jim Mattis said the missile test in itself did not bring the parties closer to a war and stressed that America's focus was on diplomatic efforts to pressure Pyongyang. "We stand ready to provide (military) options if they are necessary. But this is a purely diplomatically led (effort)," Mattis told Reuters at the Pentagon. "Diplomacy has not failed. ... Diplomatic efforts remain under way as we speak."
On Thursday, Mattis spoke with South Korean Defense Minister Han Min-koo by phone and reaffirmed Washington's commitment to the US-South Korea alliance and promising "the full range of US capabilities." He spoke with his Japanese counterpart on Wednesday.
The issue presents Trump, who took office in January, with perhaps his biggest foreign policy challenge and has put pressure on his relationship with Chinese President Xi Jinping, whom the Republican president had pressed without success to rein in Pyongyang.
China called on Thursday for restraint and made clear it did not want to be targeted by US sanctions. Chinese Vice Finance Minister Zhu Guangyao said that while China would implement relevant UN resolutions, "the US should not use their domestic laws as excuses to levy sanctions against Chinese financial institutions".
Late on Thursday, court filings made public disclosed that US authorities were trying to seize millions of dollars from companies that deal with North Korea, including the country's military, from eight large international banks.
Russia objected on Thursday to UN Security Council condemnation of the North Korean rocket launch because the US-drafted statement referred to it as an intercontinental ballistic missile, diplomats said.
Moscow has said that it believes Pyongyang fired an intermediate-range ballistic missile on Tuesday, while China has not identified the rocket launched. North Korea said it tested an ICBM and the US said that was likely true.
Trump visited Hamburg on Thursday to attend a summit of leaders of the Group of 20 developed nations. He was due to meet with Xi there. On Wednesday, Trump tweeted: "Trade between China and North Korea grew almost 40 per cent in the first quarter. So much for China working with us - but we had to give it a try!" Experts believe that this came out of frustration that Beijing has not done more to clamp down on North Korea.
However, Trump did not mention China in his remarks in Poland but his message that other countries needed to do more was clearly meant for Beijing. "President Duda and I call on all nations to confront this global threat and publicly demonstrate to North Korea that there are consequences for their very, very bad behaviour," he said.
US Ambassador to the United Nations Nikki Haley told the UN Security Council on Wednesday that the United States would propose new UN. sanctions in coming days, and that if Russia and China did not support the move, then "we will go our own path."
US officials have said the US might seek unilaterally to sanction more Chinese companies that do business with North Korea, especially banks, echoing a tactic it used to pressure Iran to curb its nuclear programme.
