This decoupling thing has elements of North Korean "Juche" (self-reliance) policy, a mind-over-matter principle edged in stone (and necessity, owing to sanctions), that doesn't serve the country well, as it forces the nation to replicate at enormous expense, what other countries can do faster/better/cheaper. It is a simple fact of life, that one country is better at this thing, and another country is better at another thing. It is inconceivable, if not delusional, that 2 countries with each double digit shares in global GDP can minimise trade with each other and prosper at the same time. Politicians everywhere should take great care, not to fall victim to their own dogma and become Kim Jong Un knock-offs.
