President Donald Trump has called for China to take action on North Korea following the firing of another missile.
Pyongyang alleged it had tested an intercontinental ballistic missile (ICBM) July 4 but international reports cast doubt on this, with some experts saying a mid-range missile was fired.
The U.S. military reported that the missile flew for 37 minutes and said this marked an improvement on previous tests, according to The New York Times.
"North Korea has just launched another missile," Trump tweeted, according to Politico. "Does this guy have anything better to do with his life? Hard to believe that South Korea and Japan will put up with this much longer. Perhaps China will put a heavy move on North Korea and end this nonsense once and for all."
The missile flew 578 miles before landing in the sea between North Korea and Japan. Analysts suggested that this indicates a North Korean missile could travel up to 4,000 miles -- far enough to reach Alaska.
Trump's call on Beijing to act followed a July 2 phone call with Chinese President Xi Jinping in which Trump stated that the United States was prepared to act alone to deal with North Korea.
Tests are being conducted on the data to determine whether North Korea did in fact fire an ICBM.
"It's a very big deal -- it looks like North Korea tested an ICBM," Jeffrey Lewis, director of the East Asia Nonproliferation Program at the Middlebury Institute of international Studies, told The Times. "Even if this is a 7,000-KM-range missile, a 10,000-KM-range missile that can hit New York isn't far off."
A number of United Nations resolutions have been adopted to prohibit North Korea from developing its missile program.
However, a North Korean statement on the test described it as "a momentous event in the history of the country" and added that it had brought "great joy" to its population.
Chinese officials condemned the test and called for dialogue.
"I have to reiterate that the current situation in the Korean peninsula is complicated and sensitive," Foreign Ministry spokesman Geng Shuang said in Beijing. "We hope all sides concerned can remain calm and restrained so that tensions can be eased as soon as possible."
President Vladimir Putin of Russia and Xi, who is currently visiting Moscow, later announced that they were proposing a plan to resolve the situation. It involves North Korea halting its missile program, while the US would have to agree to abandon its joint military exercises with South Korea.
