President Donald Trump said in a note on Twitter on Tuesday that he told China's President Xi Jinping that Beijing would get a better trade deal with Washington if it helped solve the U.S. problem with North Korea.
"I explained to the president of China that a trade deal with the U.S. will be far better for them if they solve the North Korean problem!" Trump, who held talks with Xi in Florida last week, wrote on Twitter.
"North Korea is looking for trouble. If China decides to help, that would be great. If not, we will solve the problem without them!" he added in a second note.
Trump launched a missile strike on Syria late Thursday while meeting with Chinese leader Xi Jinping at his Mar-a-Lago resort in Florida.
The move was widely interpreted as a warning to North Korea as well as retaliation for the Damascus regime's suspected sarin attack against civilians in a rebel-held town in Syria.
The United States has deployed a naval strike group -- which includes the Nimitz-class aircraft carrier USS Carl Vinson -- to the Korean peninsula in a show of force.
Trump has previously threatened unilateral action against Pyongyang if China, the North's sole major ally, fails to help curb its neighbor's nuclear ambitions
