This all started back in 1986 when china submitted a formal request in July that year to get a seat in GATT(General Agreement on Trade &Tarrif)
China being communist was eyeing towards expansion, being rejected at GATT, they send another request.
Pakistan under CPEC (China Pakistan Economic Corridor) remains the most vulnarable because of its presence in Gilgit-Baltistan region, acclaimed by India to be its territory.
Maybe one day, it is "MADE AND MANUFACTURED IN INDIA" 🇮🇳
China has never ever fulfilled all the T&C's which it accepted in 1999, as a part of agrement with USA and majorly being Tarrif policies.
Still a developing country, it takes all the possible favours from WTO, yet not an open market as of themselves.
IRONICAL SUPERPOWER
