 SEOUL, South Korea (AP) — The Latest on North Korea's nuclear test and the world reaction (all times local): 
 
 5:30 p.m. 
 
 A senior Russian diplomat has strongly condemned North Korea's latest nuclear test. 
 
 The U.N. Security Council is scheduled to hold an emergency meeting, its second in less than a week, after North Korea conducted its most powerful nuclear test to date. 
 
 In unusually strong language, Russian Deputy Foreign Minister Sergei Ryabkov on Monday urged North Korea to "stop provocative actions that destabilize the situation." 
 
 He said Moscow sees "a dangerous trend in how quickly North Korea is making progress" in its nuclear program. 
 
 Ryabkov insisted that Moscow still sees diplomacy as the only viable solution to the Korea crisis. 
 
 He said: "The one who is stronger and smarter should show restraint." 
 
 Ryabkov was speaking to Russian news agencies on the sidelines of a summit of major emerging economics in China.

 China has warned North Korea against proceeding with its reported plans to launch another ballistic missile, saying it should not worsen tensions. 
 
 Chinese foreign ministry spokesman Geng Shuang told reporters Monday that North Korea "must be very clear" that U.N. Security Council resolutions prohibit such activities. 
 
 South Korea's Defense Ministry said Monday that North Korea appeared to be planning a future missile launch, possibly of an ICBM. 
 
 In Beijing, Geng said China hopes all parties, especially North Korea, "exercise restraint and refrain from further escalating tensions." 
 
 Geng also said that China had lodged "stern representations" with the North Korean Embassy in Beijing after the North conducted its sixth nuclear test on Sunday.

 South Korea says Donald Trump's national security adviser H.R. McMaster spoke with his South Korean counterpart on Monday, a third time the two spoke since North Korea's sixth nuclear test. 
 
 South Korea's presidential office said Chung Eui-yong, President Moon Jae-in's national security director, spoke with McMaster for 30 minutes on the phone on Monday morning to discuss the latest updates on the two countries' response to the North's test and their future response. 
 
 The U.S. confirmed its strong defense commitment on South Korea and they both agreed to closely collaborate to come up with stern punitive measure against the North's provocation. 
 
 4:50 p.m. 
 
 China says President Donald Trump's threat to cut off trade with countries that deal with North Korea is unacceptable and unfair. 
 
 Trump said on Twitter on Sunday the United States is considering halting trade with "any country doing business with North Korea." His remarks came after North Korea detonated a thermonuclear device in its sixth and most powerful nuclear test. 
 
 Geng Shuang, a Chinese Foreign Ministry spokesman, told reporters at a briefing in Beijing on Monday that China regarded as "unacceptable a situation in which on the one hand we work to resolve this issue peacefully but on the other hand our own interests are subject to sanctions and jeopardized." 
 
 Geng said: "This is neither objective nor fair." 
 
 China is the North's closest ally and commercial partner.

 South Korea says the U.S. military will soon install additional missile-defense launchers at the site in southeastern South Korea in order to counter North Korea's provocations. 
 
 South Korea's defense ministry says the installation of four missile launchers of the Terminal High Altitude Area Defense system, also known as THAAD, was a "temporary" deployment as it needed to respond to the advancement of the North's nuclear and missile threats. 
 
 The ministry says the final deployment of the THAAD missile system will hinge on an environmental impact study. The U.S. anti-missile system has been a source of diplomatic tensions between South Korea and China, which fears its powerful radar may peer into Chinese territory. It has also faced opposition from local residents who say the previous administration made a hasty decision to install the U.S. anti-missile system without due procedures.

 China and other major emerging economies say they "strongly deplore" North Korea's latest nuclear test. 
 
 The leaders of Brazil, Russia, India, China and South Africa are meeting at the BRICS summit in southeastern China. The leaders adopted a declaration Monday in which they expressed "deep concern over the ongoing tension and prolonged nuclear issue on the Korean peninsula." 
 
 The text of the declaration, posted on India's Ministry of External Affairs website, also said the countries emphasized the issue should be settled through peaceful means and dialogue — echoing Beijing's long-held position.

 Japan's leader says he will seek to bolster his country's missile defense in the face of the growing North Korean threat. 
 
 Prime Minister Shinzo Abe said Monday that his government would push for adding equipment such as the U.S.-developed Aegis Ashore missile interceptor. 
 
 His comments to a meeting of top officials from the government and his ruling party came one day after North Korea conducted its biggest nuclear test to date. 
 
 Abe said Japan would maintain high caution for what he called "further provocations" from North Korea. 
 
 Japan's Defense Ministry said last week in its 2018 budget proposal that it is considering the Aegis Ashore anti-missile system.

 Egypt has condemned North Korea's nuclear test, warning of threats to regional security. 
 
 The Foreign Ministry expressed worries Monday that the escalating activity could unleash a nuclear arms race in the region. 
 
 The statement on Monday comes nearly 10 days after the U.S. announced it was withholding millions of dollars in aid to Egypt over human rights concerns. Observers, however, have noted that the move is also linked to Egypt's relations with North Korea as the U.S. continues to isolate North Korea economically and politically. 
 
 In a phone call in July, President Donald Trump gave a thinly veiled warning to Egypt's President Abdel-Fattah el-Sissi to stop its economic cooperation with Pyongyang.

 A publication of the ruling Communist Party has urged China to avoid imposing a full embargo on North Korea. The Global Times newspaper said in an editorial Monday that such a response would trigger war. 
 
 The paper said the nuclear test conducted Sunday was "another wrong choice that Pyongyang has made" in violation of U.N. Security Council resolutions. 
 
 It said China should avoid overly aggressive sanctions, as long as North Korea's tests do not contaminate China's northeastern provinces. China's Ministry of Environmental Protection says radiation monitoring data showed no impact from the test as of early Monday. 
 
 Meanwhile, leading Chinese government-backed scholar Lu Chao says China will likely agree to slap more sanctions on its ally North Korea over its latest nuclear test. But Lu asserted that dialogue remained necessary. 
 
 "The U.S should take specific and sincere actions toward North Korea instead of making enhanced threats," said Lu, of the Academy of Social Sciences in Liaoning province abutting North Korea.

 South Korean media says Seoul's military believes North Korea is readying the launch of a ballistic missile, possibly an ICBM. 
 
 Yonhap news agency reports that Seoul's defense ministry also measures North Korea's nuclear test at 50 kilotons. The detonation Sunday was the strongest ever from the North, which claimed the test was of a hydrogen bomb. 
 
 South Korea responded to the nuclear test with live-fire drills off its eastern coast Monday that were meant to simulate an attack on the North's main nuclear test site.

 12:30 p.m. 
 
 The leaders of South Korea and Japan have agreed to work together to build support for further sanctions against North Korea following its latest nuclear test. 
 
 Japanese broadcaster NHK says Japanese Prime Minister Shinzo Abe and South Korean President Moon Jae-in discussed the crisis by telephone Monday, ahead of an emergency U.N. Security Council meeting. 
 
 Abe also spoke with President Donald Trump and Russian leader Vladimir Putin late Sunday night. 
 
 Japan's Foreign Ministry said that Abe strongly encouraged Russia to respond constructively as a permanent member of the Security Council. He and Putin agreed to continue talks later this week in Vladivostok, Russia. 
 
 Abe told Trump that North Korea's nuclear test is a serious threat to Japan's security that poses a "head-on challenge" to the international community.

 Australian Prime Minister Malcolm Turnbull has called on China to bring North Korea to its "senses" following its apparent test of a hydrogen bomb. 
 
 He said China will be enforcing U.N. economic sanctions against North Korea but "there will be more that needs to be done given the affront that North Korea has shown to China" by testing its sixth nuclear device on Sunday. 
 
 Turnbull told reporters in Canberra on Monday that the risk of war breaking out on the Korean Peninsula is at its highest in over 60 years. He said China, as the North's closest ally and commercial partner, had the economic leverage to and therefore the responsibility to influence North Korea.

 South Korea's military says it conducted a live-fire exercise simulating an attack on North Korea's nuclear test site to "strongly warn" Pyongyang over the latest nuclear test. 
 
 Seoul's Joint Chiefs of Staff says the drill involved F-15 fighter jets and the country's land-based "Hyunmoo" ballistic missiles and that the released live weapons "accurately struck" a target in the sea off the country's eastern coast. 
 
 The JCS says that the target was set considering the distance to where the North's test site was and the exercise was aimed at practicing precision strikes and cutting off reinforcements.

 The U.N. Security Council has scheduled an emergency meeting after North Korea conducted its most powerful nuclear test to date. 
 
 The U.S., Japan, France, Britain and South Korea requested Monday's meeting after North Korea detonated what it called a hydrogen bomb. 
 
 It will be the Security Council's second urgent session in under a week on the North's weapons tests, which have continued in the face of a series of sanctions. 
 
 After North Korea launched a ballistic missile over Japan, the council Tuesday strongly condemned the test and reiterated demands that Pyongyang halt its ballistic missile and nuclear weapons programs. 
 
 Monday could bring additional condemnation and discussion of other potential steps. 
 
 Meanwhile, U.N. Secretary-General Antonio Guterres condemned Sunday's nuclear test. His spokesman calls it "profoundly destabilizing for regional security."

 U.S. Defense Secretary Jim Mattis is responding to North Korea's latest nuclear test by saying threats to the United States and its allies "will be met with a massive military response." 
 
 Mattis spoke at the White House on Sunday following a meeting with President Donald Trump and national security advisers. He says any response will be "both effective and overwhelming." 
 
 Mattis says the United States is "not looking to the total annihilation" of North Korea, but added "we have many options to do so." 
 
 North Korea claimed "perfect success" in an underground test of what it called a hydrogen bomb — potentially vastly more destructive than an atomic bomb. It was the North's sixth nuclear test since 2006, but the first since Trump took office in January.

 The president of the European Commission says North Korea's latest nuclear test compels the international community to unite in swift and decisive reaction. 
 
 Donald Tusk said the European Union stands ready to sharpen its policy of sanctions and invites North Korea to restart dialogue on its nuclear and missile programs without condition. 
 
 In Sunday's statement, Tusk said the EU calls on the U.N. Security Council "to adopt further U.N. sanctions and show stronger resolve to achieve a peaceful denuclearization of the Korean peninsula," adding, "The stakes are getting too high." 
 
 He said North Korea must abandon its nuclear weapons of mass destruction and ballistic missile programs in a verifiable and irreversible manner and it must cease all related activities at once.

 Turkey has strongly condemned the latest North Korean nuclear test. 
 
 In a statement published Sunday, Turkey's foreign ministry said the test was "irresponsible and provocative," while ignoring international law and endangering regional peace and security. 
 
 Turkish troops were part of a United Nations command aiding South Korea during the Korean War between 1950 and 1953. More than 700 soldiers died in the battles.

 President Donald Trump says the United States is considering halting trade with "any country doing business with North Korea." 
 
 Trump said on Twitter Sunday that the approach was under consideration, "in addition to other options," after North Korea detonated a thermonuclear device in its sixth and most powerful nuclear test. 
 
 Treasury Secretary Steven Mnuchin said Sunday that he was putting together new sanctions seeking to cut off trade with North Korea. On "Fox News Sunday," Mnuchin described Pyongyang's behavior as "completely unacceptable." 
 
 Trump is meeting with his national security team Sunday afternoon to discuss North Korea. 
 
 The president was asked if he would attack North Korea as he left a church service Sunday. He said: "We'll see."

 Russian President Vladimir Putin has spoken by telephone with Japanese leader Shinzo Abe and urged restraint in responding to North Korea's claim to have set off a hydrogen bomb test. 
 
 Putin, in China for a meeting of leaders of the BRICS economic bloc, called Abe on Sunday. 
 
 Kremlin spokesman Dmitry Peskov told journalists that Putin "said the international community could not give in to emotions, should act calmly and deliberately, and stressed that the complex settlement of the nuclear and other problems of the Korean Peninsula can be achieved exclusively through political and diplomatic means."

 North Korea has claimed a "perfect success" for its most powerful nuclear test so far, a further step in the development of weapons capable of striking anywhere in the United States. 
 
 U.S. President Donald Trump, asked if he would attack the North, said, "We'll see." 
 
 The president was meeting later Sunday with his national security team. North Korea's nuclear test was the first since Trump took office in January. 
 
 In a series of tweets, Trump said the latest provocation from the isolated communist country reinforces the danger facing America. He said "talk of appeasement" is pointless because "They only understand one thing!" 
 
 After attending church in Washington, the president made his "We'll see" comment in response to a question from reporters. ||||| WASHINGTON/BEIJING (Reuters) - President Donald Trump warned on Wednesday that the United States would no longer tolerate North Korea’s actions but said the use of military force against Pyongyang will not be his “first choice.” 
 
 His comment appeared to be in line with classified briefings to Congress in which Trump’s top national security aides - Defense Secretary Jim Mattis, Secretary of State Rex Tillerson and Dan Coats, the director of national intelligence - stressed the search for a diplomatic solution to the crisis, lawmakers said. 
 
 A senior administration official, meanwhile, said that the White House has set aside for now consideration of exiting a free trade pact with South Korea, a move being contemplated by Trump that could have complicated relations with Seoul. 
 
 In a flurry of phone calls with world leaders days after North Korea’s sixth and most powerful nuclear test, Trump and Chinese President Xi Jinping committed to “take further action with the goal of achieving the denuclearization of the Korean peninsula,” the White House said. 
 
 “President Xi would like to do something. We’ll see whether or not he can do it. But we will not be putting up with what’s happening in North Korea,” Trump told reporters, though he offered no specifics. 
 
 “I believe that President Xi agrees with me 100 percent,” he added. 
 
 Asked whether he was considering a military response to North Korea, Trump said: “Certainly, that’s not our first choice, but we will see what happens.” 
 
 Xi, who has been under pressure from Trump to do more to help curb North Korea’s nuclear and missile programs, told the U.S. president during their 45-minute call that the North Korean issue must be resolved through “dialogue and consultation.” 
 
 The focus on negotiations by China, North Korea’s main trading partner, contrasted with Trump’s assertions over the last few days that now was not the time for talks with North Korea while pressing instead for increased international pressure on Pyongyang. 
 
 The United States and South Korea have asked the United Nations to consider tough new sanctions on North Korea after its nuclear test on Sunday that Pyongyang said was an advanced hydrogen bomb. 
 
 Late on Wednesday, U.S. Treasury Secretary Steve Mnuchin indicated that if the U.N. Security Council fails to approve sufficiently strong measures, Trump could authorize him to impose sanctions on any country or entity that trades with North Korea. 
 
 “We believe that we need to economically cut off North Korea,” Mnuchin told reporters aboard Air Force One as it flew back from North Dakota, where Trump gave a speech on tax reform. “I have an executive order prepared. It’s ready to go to the president. It will authorize me to . . . put sanctions on anybody that does trade with North Korea.” 
 
 Mnuchin said that Trump would consider the order “at the appropriate time once he gives the U.N. time to act.” 
 
 He provided no further details, including whether Trump would consider slapping sanctions on China, North Korea’s largest trade partner. 
 
 Russian President Vladimir Putin insisted on Wednesday that resolving the North Korean nuclear crisis was impossible with sanctions and pressure alone. 
 
 Putin met South Korea’s Moon Jae-in on the sidelines of an economic summit in the eastern Russian city of Vladivostok amid mounting international concern that their neighbor plans more weapons tests, including possibly a long-range missile launch before a weekend anniversary. 
 
 Putin echoed other world leaders in denouncing North Korea’s latest nuclear bomb test on Sunday, saying Russia did not recognize its nuclear status. 
 
 “Pyongyang’s missile and nuclear program is a crude violation of U.N. Security Council resolutions, undermines the non-proliferation regime and creates a threat to the security of northeastern Asia,” Putin said at a news conference. 
 
 “At the same time, it is clear that it is impossible to resolve the problem of the Korean peninsula only by sanctions and pressure,” he said. 
 
 No headway could be made without political and diplomatic tools, Putin said. 
 
 MOON SEEKS SANCTIONS 
 
 Moon, who took office this year advocating a policy of pursuing engagement with North Korea, has come under increasing pressure to take a harder line. 
 
 He has asked the United Nations to consider tough new sanctions after North Korea’s latest nuclear test. 
 
 The United States wants the Security Council to impose an oil embargo on North Korea, ban the country’s exports of textiles and the hiring of North Korean laborers abroad and subject leader Kim Jong Un to an asset freeze and travel ban, according to a draft resolution seen by Reuters on Wednesday.

 Diplomats say the U.N. Security Council could also consider barring the country’s airline. 
 
 “I ask Russia to actively cooperate as this time it is inevitable that North Korea’s oil supply should be cut at the least,” Moon told Putin, according to a readout from a South Korean official. 
 
 Putin said North Korea would not give up its nuclear program no matter how tough the sanctions. 
 
 “We too, are against North Korea developing its nuclear capabilities and condemn it, but it is worrying cutting the oil pipeline will harm the regular people, like in hospitals,” Putin said, according to the South Korean presidential official. 
 
 Russia’s exports of crude oil to North Korea were tiny at about 40,000 tonnes a year, Putin said. By comparison, China provides it with about 520,000 tonnes of crude a year, according to industry sources. 
 
 Last year, China shipped just over 96,000 tonnes of gasoline and almost 45,000 tonnes of diesel to North Korea, where it is used across the economy, from fishermen and farmers to truckers and the military. 
 
 Trump and British Prime Minister Theresa May agreed in a telephone call on Tuesday that China must do more to persuade North Korea to cease its missile tests, a spokesman for May said. 
 
 ‘FREEZE FOR FREEZE’ 
 
 Sanctions have done little to stop North Korea boosting its nuclear and missile capacity as it faces off with Trump, who has vowed to stop it from being able to hit the U.S. mainland with a nuclear weapon. 
 
 China and Russia have advocated a “freeze for freeze” plan, where the United States and South Korea stop major military exercises in exchange for North Korea halting its weapons programs, but neither side is willing to budge. 
 
 North Korea says it needs to develop its weapons to defend itself against what it sees as U.S. aggression. 
 
 South Korea and the United States are technically still at war with North Korea after the 1950-53 Korean conflict ended with a truce, not a peace treaty. 
 
 China objects to both the military drills and the deployment in South Korea of an advanced U.S. missile defense system that has a radar that can see deep into Chinese territory.

– With activity around missile launch sites suggesting North Korea planned more missile tests, Jang Kyoung-soo, South Korea's acting deputy defense minister, warned parliament Monday that the North also could be planning to "fire an intercontinental ballistic missile." Seoul wasn't letting grass grow under its feet: South Korea said it was talking to the United States about deploying aircraft carriers and strategic bombers to the Korean peninsula in the wake of its sixth and largest nuclear test, Reuters reports. As the UN Security Council was set to meet later in the day to discuss new sanctions against the isolated regime, Defense Secretary Jim Mattis said that while the US wasn't looking "looking to the total annihilation" of North Korea, "we have many options to do so." One day after the North tested a powerful hydrogen bomb, the South's air force and army conducted war games that simulated a live-fire attack on the North's nuclear facility to "strongly warn" Pyongyang. The South also said it planned to deploy the four remaining launchers of the new THAAD US missile defense system, vehemently opposed by China and Russia. The US warned of "massive" military response if Seoul or its allies were threatened. Meanwhile, Russian Deputy Foreign Minister Sergei Ryabkov urged North Korea to "stop provocative actions that destabilize the situation," the AP reports. In unusually strong language, Ryabkov told reporters that Moscow sees "a dangerous trend in how quickly North Korea is making progress" in its nuclear program. He insisted diplomacy was the only solution, adding, "The one who is stronger and smarter should show restraint."
