According to Chinese state media, Mr Xi told Mr Trump in a phone call that "all relevant parties" should stop "words and deeds" that would exacerbate the situation.
The United States to protect itself and maintain global credibility has little choice but to make a disarming strike, at least against the two North Korean satellites, that might be nuclear-armed for EMP attack, orbiting over the USA, and against the dozen North Korean road-mobile ICBMs now deployed.
It's an existential question for this tiny territory now caught between President Trump and North Korea.
Kim "showed us that the rocket has the range" necessary to strike parts of the USA through recent missile tests, Ganyard said.
Trump refused to say whether he has ordered a change in military readiness.
"America stands by its allies, including Australia of course, and we stand by the United States", Malcolm Turnbull, told 3AW, an Australian radio station. And he's not going to threaten South Korea.
As North Korea's only real ally, China has more influence than any other nation over the hermit nation.
Issuing a new threat to North Korea, President Donald Trump demanded that North Korea "get their act together" or face extraordinary trouble. Normally two tests of an ICBM would not be enough to deploy it, she said. "We have tens of millions of people in this country that are so happy with what I'm saying because they're saying finally we have a president that's sticking up for our nation and frankly sticking up for our friends and our allies".
North Korea has announced plans to fire missiles into the sea near the island, a U.S. territory and key military base in the Western Pacific.
On Thursday, Trump suggested that maybe his "fury" statement "wasn't tough enough." But because of its key strategic role in the Pacific, Guam is also a target for North Korea. But he says that, until that happens, the USA "will be the most powerful nuclear nation on earth, by far".
Will New Sanctions Restrain Kim Jong Un? Maybe Not
Cambodia has previously made clear it will not back any further nuclear development efforts by North Korea. Despite tweeting last week that the USA was "done talking" about North Korea, Ambassador to the U.N.
Tension in the region has risen since the North staged two nuclear bomb tests past year and launched two intercontinental ballistic missile tests in July in defiance of world powers.
On Twitter, he said the military was "locked and loaded" if North Korea carried out its threat. They haven't quelled tensions, but could be a foundation for a more diplomacy, according to US officials and others briefed on the process.
Immediately, move more THAAD interceptors to South Korea, more Aegis anti-missile ships around North Korea and in the Gulf of Mexico, strengthening USA missile defenses.
"We are going to be increasing our budget by many billions of dollars, we'll probably be able to report that over the next week", Sputnik quoted Trump as saying.
She said: "I don't see a military solution and I don't think it's called for". "While the U.S. president insists on ramping up the war of words, there is a decreasing chance of any diplomatic solution".
Speaking in California late on Thursday, the Pentagon chief said it was his job as defence secretary to be ready for conflict. It has expressed frustration with both Pyongyang's repeated nuclear and missile tests and with behavior from South Korea and the United States that it sees as escalating tensions.
Guam, a tropical island more than 3,000 km (2,000 miles) to the southeast of North Korea, is home to about 163,000 people.
Earlier today, Trump doubled down on his pledge to bring "fire and fury" to North Korea in a shock statement.
Speaking to reporters at his golf club in Bedminster, New Jersey, Trump made clear he will respond forcefully to any North Korean attack on the USA or its allies. It has a strategically located US air base, a Navy installation that includes a submarine squadron, a Coast Guard group and roughly 6,000 USA military service members.
