A tweet by Global Times' editor-in-chief, Hu Xijin

"Based what I know, out of respect for President Trump, the US and its people, China is considering to put the drafters of the Hong Kong Human Rights and Democracy Act on the no-entry list, barring them from entering Chinese mainland, Hong Kong and Macao."

I reckon that is probably one part of possible retaliatory measures but in any case, it should be viewed as a rather soft one - but the spin on the response above is that it is done "out of respect for Trump and the US".

As such, this leads me to believe that the signing of the HK bill isn't quite putting the "Phase One" deal in jeopardy just yet.
