Sign China Shanghai, which was scheduled for September 16-18, 2021, has been postponed to 2022. The event pulled exhibitors and visitors from Australia and New Zealand. However, as travel restrictions make it impossible to invite overseas companies from these countries as well as others which are affected by COVID-19, the organizers have decided to re-schedule the show on new dates in 2022. Shanghai has a population almost the same at all of Australia. Delta strain virus has arrived there too but the vaccination rate it high. With a resident population of over 24.87 million, Shanghai has administrated 38.2 million COVID-19 vaccine doses, involving 20.56 million people, including 18.80 million people who have fully completed the vaccine process. A statement from the organizers says they will keep exhibitors and visitors updated with new developments and new dates of the show.
