Strategies for Food Security under Xi Jinping. Since coming to power, Xi Jinping''s government has made food security a national priority. Reflecting the importance Beijing places on the issue, in March 2023 a book of "Excerpts of Xi Jinping''s Discussions on National Food Security" was published by the Chinese Central Literature Publishing House.
On May 14, 1968, the first PSPS in China was put into operation in Gangnan, Pingshan County, Hebei Province. It is a mixed PSPS. There is a pumped storage unit with the installed capacity of 11 MW.This PSPS uses Gangnan reservoir as the upper reservoir with the total storage capacity of 1.571×10 9 m 3, and uses the daily regulation pond in eastern Gangnan as the lower …
