This included all 54 venues set to be used for competition at next year's delayed multi-sport event, and 30 of the 31 due to be used for training.

Hangzhou 2022's international relations department deputy director Jeff Xu provided the update at the Olympic Council of Asia (OCA) Regional Forum in Riyadh.

Xu said that all the venues had been accepted by the technical delegates for the 40 sports on the programme.

China has implemented some of the world's toughest COVID-19 restrictions which have already led to the event being pushed back by one year to new dates of September 23 to October 8 2023.

Chinese President Xi Jinping has largely persisted with a so-called zero-COVID policy which has led to numerous sporting events being either postponed or cancelled, although the Beijing 2022 Winter Olympics and Paralympics were held under a strict closed-loop management system.

International arrivals are currently required to spend five days in quarantine, followed by three days of self-testing and reporting.

Xu said that the Organising Committee would continue to be guided by Government policy, but claimed that the situation was "improving drastically".

"We are working with the OCA to produce the handbook in March and May for the defining policy," he said.

"We advise everyone coming to Hangzhou to be fully vaccinated."

National Olympic Committees (NOCs) are set to have between February 1 and March 15 2023 to declare their number of entries, and June 1 to July 15 to provide names.

Updates were provided on other key areas including accreditation, transportation, accommodation, media and broadcast services, NOC services, the Asian Gams Village and the sports programme and schedule.
