Meanwhile, Trump said he was very concerned about the situation as the missile had landed in a spot close to Japan, emphasizing his country's "ironclad commitment to defend Japan".
The Yomiuri ShimbunAlthough North Korea is acting in an utterly unbridled manner, China still remains hesitant about imposing rigorous sanctions on that country.
Over the weekend, however, Trump tweeted he was "very disappointed" in China, saying it "does nothing for us with North Korea, just talk", even after United States leaders allowed Beijing to benefit from trade deals.
The discussions in Washington come as Pyongyang continues to test intercontinental ballistic missiles.

Asked by reporters about recent statements by members of the Trump administration, including a fiery statement by U.N. Ambassador Nikki Haley saying the US would not seek an emergency session until China made a decision to act, Liu looked to put the blame on to the USA -urging North Korea and "other relevant countries" to avoid upping the rhetoric.
China's Foreign Ministry, in a statement sent to Reuters responding to Trump's tweets, said the North Korean nuclear issue did not arise because of China and that everyone needed to work together to seek a resolution.
"If they want to be a global power that takes responsibility".
The North Korean crisis has been one of the main focuses of the Trump administration.
