Xi, on the other hand, has refrained from hyper-ventilating in keeping with the traditional style of the Chinese leadership.
Since taking office, Trump has repeatedly blamed China for the continued nuclear proliferation in North Korea. The leading proponents for that tack include Trump's chief strategist Steve Bannon and top trade envoy Peter Navarro, who continue to push the President to deliver a tough opening message to Xi, according to officials.
"Something insane could happen unexpected, certainly".
Mr Trump tweeted last week that the meeting would be "very difficult" due to trade issues with China.
Xi and the Chinese side will come to the summit extremely well prepared on a wide range of complex issues confronting the two governments.
Some of the largest US companies have contributed to the billions of dollars of foreign direct investment that have poured into China over the past two decades, creating hundreds of thousands of jobs.
So, even though we hear sometimes that China's political influence may have diminished with North Korea, clearly its economic leverage has not.
There is also a perception, both in Washington and Beijing, of an ideological split in the Trump White House between a nationalistic-driven, anti-China faction and a more pragmatic group, especially in terms of trade policy. Instead of criticizing China for inaction, the White House should embrace Beijing's ban on coal and build around it a full strategy to cripple North Korea economically.
"China is the definition of North Korea's backyard", Hyten testified.
The lower house adopted the resolution with 394 votes in favour and only one against, weeks after Pyongyang tested a rocket engine and after multiple missile and nuclear tests by the Communist regime. "There are big issues of national and economic security that need to get addressed", he told reporters.
"I think this administration wants to see them act and I think they are going to pressure them to do that".
And Chinese analysts scoffed at the idea that Trump's tough talk would have any impact on Beijing's approach to its renegade neighbor. But there has been no such action, so far. For example, the Trump administration would do well not to pursue an overly aggressive policy toward China in the South China Sea, in light of the burgeoning crisis on the Korean Peninsula.
Republicans have also been talking about a border adjustment tax, which would tax American companies that import goods from other countries, including China, but Trump has wavered on whether he supports that, too.
"Our One-China policy is based on the three joint communiques with China, as well as the Taiwan Relations Act".
The United States switched it diplomatic ties from Taipei to Beijing in 1979. But, after Xi reportedly gave him the silent treatment, Trump agreed to honor the policy during a phone call.
"As President Xi knows well, THAAD is a defensive missile system critical to protecting the Korean people and, just as importantly, the tens of thousands of American troops and their families stationed in Northeast Asia from evolving North Korean capabilities", the senators said.
Those doubts came back to the forefront on Monday when some US states accused Trump's administration of illegally suspending energy efficiency standards, while Democrats amassed enough support to block a confirmation vote for Trump's Supreme Court nominee.
The official said that the USA would like to see the bilateral relationship based on reciprocity as the Trump administration wants to work with China to reduce systemic trade and investment barriers that they have created leading to an uneven playing field for the USA companies.
But on territorial issues during the meeting in Florida this week, Small on VOA's Encounters program, predicted "there won't be a consensus reached on this".
The president also has said the United States could go on its own if China does not place more pressure on Pyongyang for pursuing nuclear weapons development.
