By the way if you want to see EU's so called "might" and the way China sees them, just check out the video of the recent visit of the EU leaders to China (China-EU summit) and how they were received.
The Chinese officials didn't even receive them at their plane, these EU leaders were just put them on a bus like peasants and were brought forth to the Chinese president to kiss his hands

This is how the world sees Europe these days and when I say the world I don't just mean the East. Just check out how the US regime sees Europe which is palpable in bullshit Trump's keeps saying everywhere...
China largely represents the entire East Asia with a population of over 1B that is about thrice of that of Europe that is within 450M as estimated. China's economy do equally surpasses the entire
EU's economy which has been suffering a torturing decline in her GDP over the years.
Against this background China don't owe the EU leaders any form of overwhelming ceremonial reception beyond how it was, distinct from what the other puppet nations would have done.
Addition with how the EU allows herself to be drag around by D. Trump they shouldn't project that a country like China will offer them the highly respect they are not getting from the brown hair guy in Washington.
