At the press briefing, Tillerson told reporters that Trump had alerted Xi of the missile strike at the end of their dinner together Thursday night.
The top US envoy also said that Trump is willing to listen to and cooperate with China about North Korea, but that he also understands "it creates unique problems for them and challenges". If not, we will solve the problem without them!
In the interview, Trump said, "I do like a low-interest rate policy, I must be honest with you". "That's the first time I've heard them say that in a bilateral context", he said.
To be sure, last year, China accounted for the biggest chunk of all countries in the overall US trade deficit of $500 billion, according to the US Census Bureau.
Recognising the complexity of the issue, both sides agreed to a 100-day plan of marathon trade negotiations, which would allow the United States to cut its trade deficit without undermining existing economic ties with China.
"All of us are feeling very good about the results of this summit".
China is ready to enhance law-enforcement cooperation with the US side, said Xi, calling on the two sides to jointly combat transnational crimes such as drug trafficking, child trafficking, money laundering, cyber crime and organized crime.
There was little to show that the two leaders had come to some kind of agreement on North Korea except for the fact that Trump reiterated that Washington would go it alone - much as it did with Syria - on Thursday if China didn't pursue a more aggressive influence with Pyongyang.
In his statement, Spicer said the two sides "noted the urgency of the threat" of Pyongyang's weapons programs, "reaffirmed their commitment to a denuclearized Korean peninsula, and committed to fully implement UN Security Council resolutions". Of course, China's success in maintaining the relationship doesn't spell a US defeat.
"I think the president has authorization to use force", he said.
An official propaganda organ of the Chinese government, China Daily, celebrated the cordial atmosphere of the meetings.
Trump, Xi converge on currency, Syria as US-China ties warm
Meanwhile, in response to the increased tensions in the region, the US has responded by sending an aircraft carrier group close to the Korean peninsula.
"During the meeting the two leaders discussed this issue [of Syria]". Wang Wen, the executive dean at Chongyang Institute for Financial Studies (CIFS) at the Renmin University of China, warned in the Financial Times that protectionist measures could backfire: "To be frank, the US economy cannot afford the cost of unemployment and price increases for millions of Americans who now benefit from US-China economic ties, and who would lose their jobs and livelihoods as the inevitable effect of a trade war".
On Friday, before he strolled with the US President on the grounds of his Mar-a-Lago resort, President Xi spoke of their "many common understandings" and "deepening our friendship".
"At the moment, China needs America a lot more than how America needs China", Shia said.
He says their relationship is "outstanding".
Tillerson said that Trump told Xi, "We would be, and are, prepared to chart our own course if this is something China is just unable to coordinate with us". The Trump administration needs to strengthen economic relations with Asian economies after its decision to pull out of the Trans-Pacific Partnership (TPP) damaged U.S. credibility and possibly hampered its ability to engage in regional diplomacy.
Above all, trade and investment ties between the two countries are deeply intertwined with the rest of the world, thus any escalation in imposing protectionist measures could lead to instability in the global economy, which has been teetering in last few years.
I was surprised to hear that the summit was going ahead so soon, given Mr Trump's frequent criticisms of China. Mnuchin added that "any such transaction" would have to be reviewed by the Committee on Financial Investment in the USA, which can block sales of U.S. companies to foreign investors.
North Korea considers Syria an ally. In exchange for its concessions, China expects Trump to, at the very least, desist from any provocative move - whether it's on trade, the South China Sea, the Korean peninsula or Taiwan - while China makes a sensitive domestic leadership transition.
Trump informed Xi of the missile strike as they were dining, roughly when 59 Tomahawk missiles were hitting a Syrian airfield.
The Chinese have opposed efforts to remove Syrian dictator Bashar al-Assad from power and probably took offense at the attack, said Dennis Wilder, former senior director for Asia during the George W. Bush administration. China has already agreed to United Nations resolutions that impose heavy economic sanctions on North Korea and announced in February that it was suspending coal imports from its neighbour. So the summit's one concrete deliverable was a Chinese proposal accepted by the United States.
