"The president will tweet whatever he wants," the senior White House official told reporters aboard Air Force One shortly before Trump landed in Beijing.
"That's his way of communicating directly with the American people. Why not? So long as he can access his Twitter account, because Twitter is banned in China along with Facebook and most of the other social media."

Weibo, a Twitter-like Chinese social media platform, was ablaze Wednesday with comments about what Trump would do without his most cherished form of communication.

"Fake news. What's Twitter? This website doesn't exist," one quipped.
Others appeared to be asking for explanations about Twitter in earnest, while still others called on Trump to create a Weibo account.
"In the three days that Trump's off Twitter, someone else will surely seize the throne," commented a user on Zhihu, a question-and-answer platform akin to Quora.
