blocking chinese apps is not emulating chinsese government, emulating would be blocking all apps that are not made in US. Right now China is abusing the free trade and US is well with-in its rights to block these apps
The more apt comparison would be for the US to block all apps made by countries that aren't subservient to the US. Eg. Apps from North Korea, Iran, china, Russia, etc
You mean like this? "A special clearing house designed to allow European companies that trade with Iran to bypass newly reimposed US sanctions will be set up in Europe within months, possibly in France or Germany." [1]
