Tillerson insisted the attack on Syria proved that every time a nation breaks "international norms", the United States will carry out a response "at some point", and that North Korea needs to accept usa demands for Korean denuclearization to avoid a similar fate.
In the lead-up to the summit, China-watchers predicted that President Xi would bring with him a number of key proposals on how to reduce China's huge trade surplus with the USA, the thorniest of all bilateral issues and a key plank in Mr Trump's electoral campaign, during which he repeatedly accused China of "raping" the United States, and vowed to brand the superpower a currency manipulator. But the U.S. president later agreed to respect the "One China" policy in a telephone call with President Xi in February.
The two leaders agreed to a 100-day plan to review the trade relationship with China, to increase cooperation on ending North Korea's nuclear program, and concurred that the missile threat from North Korea had reached an "urgent stage", according to Cabinet officials who described the meetings.
Trump and Xi Jinping had a two-day summit.
Trump was meeting again with his Chinese counterpart Friday, with US missile strikes on Sy.
CNN reported on Sunday that USA warships were en route to the Korean Peninsula due to provocations from North Korea.
The US began the deployment of the sophisticated missile defence system in South Korea last month to counter North Korea's increasing aggression in the region.
PYONGYANG, North Korea (AP) - The U.S. airstrikes this week were aimed at a Syrian air base, but nearly certainly got the attention of another adversary - North Korea.
Commerce secretary Wilbur Ross said that "the most interesting thing to me was they expressed an interest in reducing their net trade balance because of the impact it's having on money supply and inflation".
The "US-China Comprehensive Dialogue will be overseen by the two presidents", Tillerson said, and will be based on the "four pillars" mentioned above. DPRK stands for North Korea's official name, the Democratic People's Republic of Korea. "These sanctions are very important and we will use them to the maximum effect".More news: Neymar sent off in Barca loss, Atletico draws at Real Madrid
As a candidate and president, Trump has taken an aggressive posture toward China, labeling Beijing a "tremendous problem" and arguing that lopsided trade deals with China shortchange USA businesses and workers.
He said Trump also raised U.S.concerns about China's activities in the South China Sea.
The question then arises as to what impact the USA president's willingness to exercise his military muscle may have on China's thinking.
Chinese President Xi Jinping had just finished a steak dinner with President Donald Trump in a gilded dining room at the Mar-a-Lago resort in Florida when Mr. Trump told him that dozens of US cruise missiles had just rained down on an airfield in Syria, a fiery display of USA military might that formed an awkward backdrop to a summit meant to introduce the leaders of the world's two largest economies.
"They have indicated that they will, and I think we need to allow them time to take actions", Tillerson said. He noted the historic responsibility of both countries - the world's largest economies and emerging military rivals - to work toward peace and stability. Trump publicly announced the attacks after Xi had left the dinner.
Trump has threatened unilateral action against the reclusive communist state, a threat that appeared more palpable after Thursday's strike on a Syrian airfield following an apparent chemical attack.
While China has clearly lost patience with Pyongyang's nuclear provocations, it is extremely wary of any response that might bring about North Korea's collapse and chaos on its doorstep.
"This man who is now in office in America claimed that he wanted to fight terrorism but today all terrorists in Syria are celebrating the U.S. attack", Rouhani said in a speech aired by state television.
Russian Federation might even see an advantage in the strike, said Andrew Tabler, a senior fellow at the Washington Institute.
