No "blockade" caused the Great Chinese Famine, except that carried out by the Communist government itself (starving the people of the country to death).
The reality is it's just one of 100s of centrally created false western narratives you may have fallen for.
If you are in the US, I cant completely blame you. There are too many drug dealing and human trafficking family fortunes in the US ruling class for the truth about one of their largest crime spree victims to easily emerge. African history is another victim of similar fraud.
Communist policies caused the Great Chinese Famine. And many other man-made famines.
No, you're not. You're a denialist and Communist apologist.
