OP's heads up is very concerning as I am frequently overseas for work. So now it's looking like our government is the #2 freak show right behind China? Stocking up on popcorn while I wait for more detail / facts.
I don't buy into all the conjecture about the need for burner phones etc. Use a VPN for your browsing, clear your cache and history periodically, and GTG. I had no problem getting gmail nor even NES and other firearm enthusiast sites in China via VPN. Over the last 10 years I've regularly visited over 30 countries including Russia and China and am usually well into the interior of these countries. China was getting awful in terms of surveillance cameras everywhere, no acceptance of 'Western' credit cards at businesses anywhere else on the planet would accept them, and some other crap I don't miss. I have had many great trips there and my team has been very successful, but I hope I never need to go back. Everywhere else was fine and in many or most cases significantly better in terms of security than any of our Dem controlled shithole cities. Keep in mind I'm going to countries with a good industrial base and am not going anywhere on the African continent nor to the 'stans.
