Sadly, I doubt that will happen.
A gentler approach would be a well designed cross border emission tax. This could make operation of these plants economically impractical.
Merely adding a new tax would be the most regressive solution available, as it disproportionately hurts the poorest- the consequences would take longer but could end up just as severe. Maybe they dont have access to plentiful natural gas, or grid storage for renewables. Maybe they simply dont have an economy healthy or government free enough of corruption to invest in the capital required to transition.
A more reasonable approach would be to set up a program that fronts the necessary investments while letting the locals retain control... effectively a free loan. It would certainly meet the criterion of "gentler", at least, and probably cheaper than fuelling the planes and the bombs as well- those things are crazy expensive.
Germany in particular made the stupid decision of shutting down nuclear plants (Fukushima overreaction) and it is pushing this narrative of being a green energy country… to me it sounds like an easy problem to solve once there is enough political attention.
Most likely you fell victim to American newspapers lying to you that Germany is pushing a green narrative. After all they lied about Germany moving back to coal. What happened is that Germany willingly delayed reductions in CO2 emissions. It clearly cared about the nuclear shutdown more than the coal shutdown. However, the articles are always about how emissions went up "because more coal" when that never happened. It's lies upon lies.
Germany is a country that is standing still, neither getting better nor worse and likes it that way. It's not green and nobody pretended that it is green.
What should have happened 20-60 years ago is modular LFTR reactors, they had them at Oak Ridge. Closet sized reactors could probably scale quickly.
> “Another major reason is that many high-carbon production chains were outsourced from developed nations to Chinese cities, thus increasing the export-related emissions of the latter.”
The solution possibly is something more radical than what you're thinking, because the PRC forcing emissions reductions and driving up manufacturing costs could just cause these industries to jump to the next exploitable developing region. I'm thinking more along the lines of strategies to reduce consumerism in general, or match global product prices to their "true" cost considering environmental damage - ideas most pro-infinite-growth capitalists find untenable.
