Mere hours after President Trump tweeted that US intelligence had confirmed the buildup of Chinese troops on the border with Hong Kong,
US defense officials warned that Beijing had refused two US Navy ships permission to make port stops in Hong Kong in the coming weeks,
a sign that President Xi is none too pleased with how the US has handled itself during the anti-extradition bill protests that have swept Hong Kong over the past ten weeks.
Beijing has repeatedly warned the US to stop interfering with Taiwan and Hong Kong, or else face consequences, including the implicit threat of force.
