China to make 'substantial' COVID policy changes soon - ex-govt expert

China will make substantial changes to its 'dynamic-zero' COVID-19 policy in coming months, a former Chinese disease control official told a conference hosted by Citi on Friday, according to a recording of the session heard by Reuters. Separately, three sources familiar with the matter said China may soon further shorten quarantine requirements for inbound travellers. Zeng Guang, former chief epidemiologist at the Chinese Centre for Disease Control and Prevention who has remained outspoken on China's COVID fight, said the conditions for China opening up were 'accumulating', citing new vaccines and progress the country had made in antiviral drug research.
