Beijing is buzzing over how US President Donald Trump will interact with Chinese President Xi Jinping. I was in the CGTN studio as Air Force One touched down in Beijing, watching Trump and First Lady Melania greeted on the tarmac. 

Unlike former US President Barack Obama's 2016 arrival at the G20 Summit in Hangzhou, the arrival stairs met Trump's aircraft in timely fashion. That – combined with the lack of controversial tweets from the prolific social media president – has Trump's first state visit off to a good start.

In fact, Trump graciously teased his own arrival in Beijing via Twitter: "Leaving South Korea now heading to China. Looking very much forward to meeting and being with President Xi!"

Chinese officials say this will be a "state visit-plus." That means special events that go beyond the standard red carpet treatment for honored guests. And, expect some big business deals and plenty of friendly photo ops. 

But Trump being Trump, my colleagues have been wondering if he'll say or do something unexpected. Ben Dalton of TV Tokyo recalled that the last time the two leaders met, at Mar-a-Lago, the US launched a missile attack against Syria.

Gabi Biesinger of ARD German Radio told me she was curious to see if Trump would bring the fiery tone from his UN speech to the region. Or if he would change it once he set foot in Asia. The president has appeared more restrained. He didn’t call Kim Jong Un "Rocket Man" during his speech in Seoul. And he didn’t threaten to "totally destroy” the place. But he did call Pyongyang "a hell that no person deserves."

So did Trump change his tone? "I think he really did," Biesinger said.
