According to the EU, the basis of their DS611 complain against China at the WTO is that:
Since August 2020, Chinese courts have been issuing decisions – known as ‘anti-suit
injunctions’ – to exert pressure on EU companies that have high-tech patents and to
prevent those companies from rightfully protecting their technologies. Chinese courts
also use the threat of heavy fines to deter European companies from going to foreign
courts. This has left European high-tech companies at a significant disadvantage when
enforcing their rights. Chinese manufacturers request these anti-suit injunctions to benefit
from cheaper or even free access to European technology.
(Why) has China not used these ‘anti-suit injunctions’ before? Is there some new Chinese law that enables these injunctions, or some high-level Chinese court decision, setting precedent etc.? Or have just EU companies become more assertive than before?
