Chinese organisers said Wednesday there had been "a lot of difficulties" but Asian Games venues were ready for the pandemic-delayed competition with 100 days to go.

The Games in Hangzhou were due to take place in September 2022 but were postponed by a year because of China's strict Covid rules.

Beijing abruptly dropped its zero-Covid measures in December and organising committee vice-chairman Zhou Jinqiang said Wednesday: "All preparations have entered the sprint stage."

The Games, one of the world's largest multi-sport events, begin on September 23 and last two weeks.

All 56 competition venues are ready but organising committee official Chen Weidong said that the pandemic "brought a lot of difficulties to our venue construction".

Foreign technical staff had been unable to enter China previously and problems had to be sorted out over video calls, Chen said.

China's status as a sporting destination took a severe hit during the first three years of the pandemic, when snap lockdowns and travel rules saw almost all international events cancelled in the country.

The Asian Games typically attract more than 10,000 athletes from across the region.

Zhou said many countries were sending their largest-ever delegations this year, with China's team boasting more than 900 competitors.

Hangzhou is a prosperous tech hub just south of Shanghai.
