I have a major discovery! Trump's visit to China might be from April 22-26. During Trump's visit to China in 2017, the White House press corps stayed at the China World Hotel, which has also hosted many diplomatic receptions, as well as the China World Trade Center Hotel. Coincidentally, it's impossible to book a room during those days. Trump also mentioned the other day that his visit to China has been postponed by about a month, which is about right.
