Europeans have been providing chinese with technology for decades. From rolling stocks ( high speed rail initially uses siemens, bombardier tech), planes ( arj21 is a copy of mcdonnel Douglas md80 which was once assembled in china and crj919 a copy of airbus a320 which is being assembled in china) and europeans will not stop as china is a huge profit generator.
Mini cars are now built exclusively in China after its UK plant shut down recently. Merc, bmw, audi, vw made enormous amount of money in china.
If europe shuts, these corporation will thrive in china.
