General Joseph Dunford, chairman of the U.S. Joint Chiefs of Staff, will meet with President Moon Jae-in in Seoul on Monday amid escalating tensions over North Korea's nuclear program, according to an official with South Korea's Blue House.
The US is ready along with its allies to apply the full range of diplomatic, economic and military measures to stop the North Korean nuclear menace, President Donald Trump told his French counterpart Emmanuel Macron on Satruday.
This week, Trump has issued stern warnings to North Korean dictator Kim Jong Un.
And that doesn't mean talk hasn't been tough - the US has been speaking forcefully to North Korea all this time, said Ellen Tauscher, former USA under secretary of state for arms control and global security under President Barack Obama.
Earlier this week, France had praised Trump's "determination" in standing up to Pyongyang.
In an editorial on Saturday, North Korea's Minju Joson newspaper said that the US "finds itself in an ever worsening dilemma, being thrown into the grip of extreme security unrest by the DPRK". Trump also said the USA was considering tighter sanctions against North Korea.
Trump said he would consider negotiations with North Korea and declined to discuss the possibility of a preemptive strike against Pyongyang. "Nobody loves a peaceful solution better than President Trump".
The United Nations Security Council just unanimously passed new, stronger sanctions against North Korea's nuclear program.
Terence Roehrig, a national security affairs professor at the U.S. Naval War College in Newport, Rhode Island, said Trump's posture suggested he was trying to dissuade Kim from further provocations rather than setting the stage for a U.S. military strike.
The two leaders also reiterated a commitment to the denuclearization of the Korean Peninsula.
Chinese state media say President Xi Jinping, in a call with President Donald Trump, said all sides should avoid rhetoric or action that would worsen tensions on the Korean Peninsula. For one, they didn't want to put somebody in a corner.
