China does the same, not just with the US. Think about that. Anyway, games of chicken are just games.
Invasion...well, the US has invaded more countries than Russia. Think about that.
China, in the modern era, has invaded Tibet, Russia (USSR), Korea, Vietnam and India. They claim ownership over Taiwan, and are willing to invade if necessary. They claim all the seas in SE Asia, no matter how remote from China they may be, and are increasingly sending in their military to de facto claim the islands from weaker countries. They have threatened Japan countless times and initiated violent anti-Japanese riots, though they have been quiet in that regard recently, mainly because they have their hands full with Trump. They are a growing power, whereas Russia is a shrinking former power with vast empty spaces and drunk and broken old men and women.
