I am aware of this. India has been a market economy since the 90s. Is almost 30 years not enough for the magic of markets to improve the situation?
Regarding China, "legal status" is irrelevant. Prices in China are set via market mechanisms. That is a market economy, period. Your link boils down to this:
> According to the EU, China subsidizes its industries to a great extent, particularly steel and aluminum, making their sales prices in the international market unfair.
This is essentially saying China is using market mechanisms that the EU does not like.
Moreover, according to https://en.wikipedia.org/wiki/Socialist_market_economy#Marke..., "Julan Du and Chenggang Xu analyzed the Chinese model in a 2005 paper to assess whether it represents a type of market socialism or capitalism. They concluded that China's contemporary economic system represents a form of capitalism rather than market socialism...."
Rectified.
In response to your edit: "Currently a majority of North Koreans are dependent on markets for their survival." See https://en.wikipedia.org/wiki/Jangmadang. North Korea is also a market economy.
In what way has the US interfered in South Korea or Japan since 1950? How does that compare to being sanctioned and embargoed by every major Western nation? Would you like to hear about Cuba instead?
