While hosting Chinese President Xi Jinping, the United States launched an airstrike against Syria in response to that country's use of chemical weapons.
President Donald Trump condemned the attack earlier in the day and addressed the nation by making a brief statement.
"On Tuesday, Syrian dictator Bashar al-Assad launched a horrible chemical weapons attack on innocent civilians. Using a deadly nerve agent, Assad choked out the lives of helpless men, women, and children. It was a slow and brutal death for so many. Even beautiful babies were cruelly murdered in this very barbaric attack. No child of God should ever suffer such horror," Trump said, in part.
Earlier in the day, dozens of supporters, protesters and spectators lined the streets in Palm Beach County on Thursday as they awaited the arrival of President Donald Trump and Chinese President Xi Jinping.
Xi was the first to arrive in West Palm Beach Thursday afternoon and was greeted by Secretary of State Rex Tillerson. Trump arrived to South Florida about an hour later, accompanied by First Lady Melania Trump, Ivanka Trump and the first daughter's three children.
"I don't care about the politics and the economics. I'm here just enjoying standing here, enjoying American culture," Chinese foreign exchange student Qiqi Zng said.
Those in red called themselves supporters while people dressed in yellow, including many Vietnamese-Americans, were in Palm Beach County to protest various issues involving the Chinese government.
"To bring an end to the persecution in China, because Dafa has been persecuted in China since 1999," one protester, Dzifa Amoa, said.
Some of the Vietnamese protesters told Local 10 News reporter Andrew Perez that they are pro-Trump, and are protesting "Chinese aggression."
Nearly 2,000 Chinese-Americans lined up along the street near the Eau Palm Beach Resort & Spa to greet Xi's motorcade. Fifty buses brought people in from Broward, Miami-Dade and Palm Beach counties.
Most of the group were supporters, who came to witness the historic moment.
"I would love to see two nations come together, especially as a Chinese-American," one woman said.
Trump and the Chinese president have a lot to talk about in a short period of time, with North Korea at the top of the agenda.
Trump wants China's help ending North Korea's testing of nuclear weapons.
Trade between the U.S. and China is next on the list.
"I think it's great (that) he comes to the U.S. and sees how people live and maybe take something positive back with him," one person said.
They differ on political issues, but most agree that only good can come of China's president coming to America.
His visit is a costly one, though, forcing Palm Beach sheriff's deputies to work overtime, local businesses to shut down and unprecedented security measures to be put in place.
Before flying to the Winter White House, Trump spent the morning honoring wounded warriors.
"Our way of life continues because of men and women who are willing to sacrifice anything and everything to protect their fellow warriors," Trump said.
