When it comes to reopening China from Covid, I actually stumbled upon this article:
Furtune here reports on Guangzhou papers article where Zhong Nanshan, one of China’s top epidemiologists and government advisers, said: “Why are we still employing strict measures to prevent and control the disease?” Zhong asked in an interview with
Southern Weekly, a newspaper based in Guangzhou. “Our vaccination rate has not reached 80%–85% yet.”
While not a confirmation in itself, that quote could shed some light as to conditions that China desires to start changing its zero-covid policy.
