While this post should enjoy the benefit of doubt that every argument may have its own merits or shortcomings and there is generally two sides story for nearly everything, what about the US and European sanctions of Russia in the past two years or so? Have they run any risks in losing their international leadership? Are they justified in any way?

If yes to the second question, then why China should be condemned if it takes measures in response to its own security or to an increased risks to its security? Should China simply ignore any such increased risks?
