(CNN) North Korea tested an intercontinental ballistic missile Friday that appears to have the range to hit major US cities, experts say, and prompted a fresh round of condemnation from the United States, China, Japan and South Korea. 
 
 A combination of US, South Korean and Japanese analyses of the launch from Mupyong-ni, near North Korea's border with China, shows the missile flew about 45 minutes, going 3,700 kilometers (2,300 miles) high and for a distance of 1,000 kilometers (621 miles). 
 
 If the missile were fired on a flatter, standard trajectory, it would have major US cities such as Los Angeles, Denver and Chicago well within its range, with the possible ability to reach as far as New York and Boston, according to David Wright , a missile expert at the Union of Concerned Scientists. 
 
 However, early analysis of Friday's test cannot determine how heavy a payload the missile was carrying in its warhead, Wright said. The heavier the payload, the shorter the range. 
 
 South Korea's joint chiefs of staff said they estimate the missile tested Friday is more advanced than one launched earlier this month based on the range it traveled. Experts had said that test showed Pyongyang had the ability to hit Alaska 
 
 President Donald Trump condemned the missile launch and said the United States would act to ensure its security. 
 
 "Threatening the world, these weapons and tests further isolate North Korea, weaken its economy and deprive its people," Trump said in a written statement. "The United States will take all necessary steps to ensure the security of the American homeland and protect our allies in the region." 
 
 Kim calls weapons program a 'precious asset' 
 
 Pyongyang's state-run Korean Central News Agency said Saturday that the latest missile launch was a Hwasong-14, the same missile tested earlier this month. 
 
 Friday's test was designed to show the Hwasong-14's maximum range with a "large-sized heavy nuclear warhead," it said, adding that Washington should regard the launch as a "grave warning." 
 
 North Korean state media was quick to tout the missile test as a success, with video and stills showing leader Kim Jong Un overseeing the launch and celebrating with the troops involved. 
 
 North Koreans hailed the test-firing, the news agency said. Kim Yu Chol, a researcher at the State Academy of Sciences, called the achievement "another great victory which dealt a heavy blow to the US imperialists and its vassal forces." Jo Son Hyang, a resident of Pyongyang's Rangnang District, said the "future of the country is bright" now that it has a "powerful sword for keeping peace."

 Kim was quoted as saying "the whole US mainland" is now within North Korea's reach. He called Pyongyang's weapons program "a precious asset" that cannot be reversed or replaced, according to the agency. 
 
 In the wake of the test, the US Joint Chiefs of Staff chairman, Gen. Joseph F. Dunford Jr., and Adm. Harry Harris, commander of US Pacific Command, called the South Korean Joint Chiefs of Staff chairman, Gen. Lee Sun Jin, to express "ironclad commitment" to the US alliance with South Korea and discuss military response options. 
 
 Hours after that call, the US and South Korean military conducted a live-fire exercise as a show of force in response to the test, according to Pentagon spokesman Capt. Jeff Davis. The exercise included firing missiles into the ocean. 
 
 Both militaries conducted a similar show of force after North Korea's first ICBM test in early July. 
 
 If North Korea's assertions about Friday's test are true, Pyongyang may be even more advanced in its missile program than previously thought. Earlier in the week, a US official told CNN the United States believed that North Korea would be able to launch a reliable nuclear-capable intercontinental ballistic missile by early 2018. 
 
 The official said that while North Korea can currently get a missile "off the ground," a lot of undetermined variables remain about guidance, re-entry and the ability to hit a specific target. 
 
 China condemns launch 
 
 China, a longtime North Korean ally, issued a statement Saturday condemning the missile launch and asked Pyongyang to "stop taking actions that would escalate tensions" on the Korean Peninsula. 
 
 "The UN Security Council has clear regulations on North Korea's launch activities that use ballistic missile technologies. China is opposed to North Korea's launch activities in violation of UN Security Council resolutions and against the will of the international community," Chinese Foreign Ministry spokesman Geng Shuang said. 
 
 Beijing's statement reiterated its long-held position on North Korea's missile program. 
 
 US Secretary of State Rex Tillerson said China and Russia need to do more to stop North Korea. 
 
 "As the principal economic enablers of North Korea's nuclear weapon and ballistic missile development program, China and Russia bear unique and special responsibility for this growing threat to regional and global stability," Tillerson said in a statement. 
 
 After speaking Saturday with Tillerson, Japanese Foreign Minister Fumio Kishida said Tokyo would join Washington in new appeals to those countries to stop North Korea. 
 
 The missile splashed down about 200 kilometers (120 miles) west of the Shakotan Peninsula of Japan's northernmost main island of Hokkaido, well within Japan's Exclusive Economic Zone, Kishida said. 
 
 Not everyone agrees that North Korea launched an ICBM. The Russian Defense Ministry said its tracking indicated the weapon was a "medium-range ballistic missile," Russian state news agency Tass reported Friday. 
 
 Nuclear-capable missile? 
 
 Michael Elleman of the International Institute for Strategic Studies estimated a range of at least 9,500 kilometers (5,900 miles) for the missile, according to Reuters news agency -- less than that estimated by Wright, but still potentially putting Los Angeles within reach.

 "The key here is that North Korea has a second successful test in less than one month," he said. "If this trend holds, they could establish an acceptably reliable ICBM before year's end." 
 
 North Korea has seen a year of rapid progress in its missile program. 
 
 Pyongyang has carried out 12 missile tests since February and conducted its first test of an ICBM on July 4 -- which it says could reach "anywhere in the world." 
 
 "North Korea is slowly morphing into a nuclear and missile power right before our very eyes," said Harry J. Kazianis, director of defense studies at the Center for the National Interest and an expert on North Korea. 
 
 "North Korea will continue to test over and over again its missile technology and nuclear weapons in the months and years to come in order to develop the most lethal systems it can," Kazianis said. "You can bet every time they do tensions will continue to rise. This is what makes the situation on the Korean Peninsula as dangerous as it is." 
 
 Trump urged to respond 
 
 Less than six years in power, Kim has tested more missiles than his father and grandfather combined. 
 
 The latest test has spurred calls for a response from the Trump administration. 
 
 "North Korea's latest missile test shows the Trump administration's actions are not changing North Korea's behavior and it's time for the President to articulate a comprehensive strategy to the American people -- so far he's failed to do that," Democratic Rep. Ted Lieu told CNN on Friday. 
 
 Administration officials have warned that "all options are on the table" but a clear path forward has yet to materialize. 
 
 Doug Bandow, a senior fellow at the Cato Institute who specializes in foreign policy, told CNN that North Korea's missile launch shows its leaders are "absolutely committed to their missile programs" and not interested in tempering their activities. 
 
 Bandow, who visited North Korea last month, said the regime is convinced that developing its missile program as a nuclear deterrent is absolutely necessary. It's a mindset, he said, that puts pressure on Trump, who finds himself in a situation with no good choices. ||||| SEOUL/NEW YORK (Reuters) - The United States flew two supersonic B-1B bombers over the Korean peninsula in a show of force on Sunday and the U.S. ambassador to the United Nations said China, Japan and South Korea needed to do more after Pyongyang’s latest missile tests. 
 
 North Korea said it conducted another successful test of an intercontinental ballistic missiles (ICBM) on Friday that proved its ability to strike America’s mainland, drawing a sharp warning from U.S. President Donald Trump. 
 
 Trump’s ambassador to the United Nations Nikki Haley said on Twitter on Sunday that the United States was “done talking” about North Korea, which was “not only a U.S. problem.” 
 
 “China is aware they must act,” Haley said, urging Japan and South Korea to increase pressure and calling for an international solution. 
 
 China, the North’s main ally, said it opposed North Korea’s missile launches, which it said violate UN Security Council resolutions designed to curb Pyongyang’s banned nuclear and missile programs. 
 
 “At the same time, China hopes all parties act with caution, to prevent tensions from continuing to escalate,” China’s foreign ministry said in a statement on Saturday. 
 
 Early in his presidency, Trump met with Chinese President Xi Jinping and had expressed hope Beijing would use its economic clout to curb North Korea’s nuclear ambitions. 
 
 But on Saturday, Trump said on Twitter that he was “very disappointed in China” which he said profits from trade with the United States but does “NOTHING for us with North Korea, just talk. We will no longer allow this to continue,” he said. 
 
 DIRECT RESPONSE 
 
 North Korean leader Kim Jong Un personally supervised the midnight test launch of the missile on Friday night and said it was a “stern warning” for the United States that it would not be safe from destruction if it tries to attack, the North’s official KCNA news agency said. 
 
 North Korea’s state television broadcast pictures of the launch, showing the missile lifting off in a fiery blast in darkness and Kim cheering with military aides. 
 
 The missile test came a day after the U.S. Senate approved a package of sanctions against North Korea, Russia and Iran. 
 
 The B-1B flight was a response to the missile test and the July 3 launch of the “Hwasong-14” rocket, the Pentagon said. The bombers took off from a U.S. air base in Guam, and were joined by Japanese and South Korean fighter jets during the exercise, according to the statement. 
 
 “North Korea remains the most urgent threat to regional stability,” Pacific Air Forces commander General Terrence J. O’Shaughnessy said in a statement.

 “If called upon, we are ready to respond with rapid, lethal, and overwhelming force at a time and place of our choosing.” 
 
 Also on Sunday, the U.S. Missile Defense Agency announced the United States had successfully shot down a medium-range missile in the latest test of its THAAD missile defense program which is designed to protect the country against potential threats from countries such as North Korea and Iran. 
 
 The test was planned well before the rising tensions with North Korea and involved a medium-range missile, not the long-range types being tested by the North Koreans. 
 
 FAR REACH 
 
 The Hwasong-14, named after the Korean word for Mars, reached an altitude of 3,724.9 km (2,314.6 miles) and flew 998 km (620 miles)for 47 minutes and 12 seconds before landing in the waters off the Korean peninsula’s east coast, KCNA said. 
 
 Western experts said calculations based on that flight data and estimates from the U.S., Japanese and South Korean militaries showed the missile could have been capable of going as far into the United States as Denver and Chicago. 
 
 David Wright of the U.S.-based Union of Concerned Scientists wrote in a blog post that if it had flown on a standard trajectory, the missile would have had a range of 10,400 km (6,500 miles). 
 
 U.S. Senator Dianne Feinstein, a leading Democrat on the Senate intelligence committee, said she saw the test as “a clear and present danger to the United States.”

 “I think the only solution is a diplomatic one. I’m very disappointed in China’s response, that it has not been firmer or more helpful,” Feinstein told CBS television’s “Face the Nation,” urging the administration to begin talks with the North. 
 
 U.S. intelligence officials assess that even if North Korea does develop a reliable, nuclear-capable ICBM, which some say it remains several steps short of doing, the weapon would be almost useless except to deter the conventional attacks that Kim fears. 
 
 Intelligence experts have concluded that Kim will not abandon his pursuit of a deliverable nuclear weapon. 
 
 “Kim is determined to secure international recognition of the North as a nuclear armed state, for the purposes of security, prestige, and political legitimacy,” says the National Intelligence Council’s January Global Trends report. ||||| President Trump tweeted Saturday night that he's "disappointed" in China, and that country does "NOTHING for us" when it comes to North Korea. 
 
 "I am very disappointed in China. Our foolish past leaders have allowed them to make hundreds of billions of dollars a year in trade, yet... they do NOTHING for us with North Korea, just talk," Mr. Trump tweeted.

 "We will no longer allow this to continue," he added. "China could easily solve this problem!" 
 
 The tweets marked the latest case of Mr. Trump urging Chinese President Xi Jinping to do more regarding North Korea, which on Friday tested an intercontinental ballistic missile. 
 
 When asked about his relationship with Xi at a press conference with French President Emannuel Macro earlier this month, Mr. Trump called Xi "a friend," but added, "we asked him for some assistance with respect to North Korea, probably he could do a little bit more but we'll find out."

 China has said that it shouldn't be held responsible for solving the nuclear standoff with North Korea, and that it doesn't hold the key to resolving the issue. 
 
 The Chinese Mission to the U.N. sent CBS News late Sunday a statement by the Chinese Foreign Ministry that said, "China is concerned about the current developments." 
 
 It added that North Korea should "abide by the relevant resolutions of the [United Nations] Security Council and stop taking action that could lead to further escalation of the situation on the peninsula." 
 
 The intercontinental ballistic missile North Korea tested Friday flew longer and higher than the first one the country tested, according to its wary neighbors, leading analysts to conclude that a wide swath of the U.S. including Los Angeles and Chicago is now within range of Pyongyang's weapons. 
 
 Japanese government spokesman Yoshihide Suga has said that the missile flew for about 45 minutes -- about five minutes longer than the ICBM that was test-fired on July 4. 
 
 Following the launch, the U.S. conducted a missile defense test Sunday, using a Terminal High Altitutde Area Defense (THAAD) anti-missile system in Alaska. The U.S. Air Force launched a medium-range ballistic missile over the Pacific Ocean, and the THAAD system -- in Kodiak, Alaska -- "detected, tracked and intercepted the target," the U.S. Missile Defense Agency said in a statement Sunday. 
 
 Although several U.N. Security Council members were expecting the U.S. to take the lead in calling for an emergency meeting this week to respond to North Korea's second missile launch in a month, U.S. Ambassador Nikki Haley said on Sunday that "there is no point in having an emergency session if it produces nothing of consequence," CBS News' Pamela Falk reports. 
 
 The U.S. and China have been negotiating over the terms of a possible new resolution against North Korea, but after the July 4 launch, the Council didn't produce a press statement condemning North Korea actions, because of divisions on the Council. ||||| The U.S. military conducted a successful test of its Terminal High Altitude Area Defense (THAAD) missile system on Tuesday by shooting down a simulated intermediate-range ballistic missile over the Pacific Ocean. The test signals an improvement in the defense system, which before Tuesday had only intercepted shorter-range missiles. While the simulation was planned for months, it comes amid a growing international threat from North Korea, which tested its first intercontinental ballistic missile (ICBM) on July 4. 
 
 On Tuesday, the U.S. Missile Defense Agency released a statement claiming that the latest test “bolsters the country’s defensive capability against developing missile threats in North Korea and other countries around the globe.” North Korea is widely believed to be developing an ICBM capable of reaching the U.S. mainland. Experts say the nation’s latest tests puts Alaska within striking distance, but is not yet capable of reaching the lower 48 states. 
 
 Tuesday’s test was carried out in Kodiak, Alaska, and shot down a ballistic missile target from an aircraft flying north of Hawaii. The simulation adds to a perfect track record of THAAD missile launches since the U.S. resumed testing in 2005. Thus far, THAAD has proven more successful than the nation’s Ground-based Midcourse Defense (GMD) system, which is designed to target an ICBM. Even after a successful test launch in May, the GMD system has only achieved a 55 percent success rate. While the Pentagon previously reported that the system has a “limited capability to defend the U.S. homeland,” they have since claimed that the U.S. is capable of defending itself against a small number of ICBMs.
– One day after North Korea tested a missile that experts say has the range to hit major cities in the United States, President Trump took to Twitter to express his disappointment with China for doing "NOTHING for us" when it comes to the rogue country, CBS News reports. "I am very disappointed in China," Trump tweeted around 7:30 on Saturday night. "Our foolish past leaders have allowed them to make hundreds of billions of dollars a year in trade, yet they do NOTHING for us with North Korea, just talk." Two weeks earlier a spokesman for the Chinese foreign ministry said that China does not "hold the key to resolve" the Korea issue, the Atlantic reports. Experts in the US, South Korea, and Japan say the intercontinental ballistic missile launched from near North Korea's border with China on Friday flew about 2300 miles high and for a distance of 621 miles, CNN reports. All told the missile was in the air for about 45 minutes. Had the missile been fired on a flatter trajectory, major US cities like Los Angeles and Chicago would have been in its range, possibly even New York City and Boston. In response to the test the US flew two supersonic B-1B bombers over the Korean peninsula in a show of force Sunday, Reuters reports. The US also hopes to set up an emergency meeting of the UN Security Council this week to discuss the issue.
