Earlier quoted context omitted.
We can no longer say "the west" and expect a unified response - brexit, the constant attacks on member nations of NATO by Trump, The Iran deal that Europe still backs but the US doesn't. There's a reason Russia and China are bold right now. EDIT: I get it, it's politically charged, but I remind everyone to discuss, rather than downvote, based on your own political opinion.
Most of the West wants to appease China. What response are you talking about. It's not standing in front, that's for sure. EU silence is deafening, except for some weak, mild comments here or there. China's diplomacy barks back, and EU commissioners become silent.
The hope is that long-term economic integration will progressively reduce these problems, by turning "national spheres of influence" into "European spheres of influence". But at the moment, EU foreign-policy mechanisms (and appointees...) are fairly weak. We'll see what happens after we digest the loss of Britain, which was an extremely vocal (and followed / respected) member on these topics. Maybe we'll finally grow up a bit.
