The upcoming Shenzhen World University Games would become the "biggest" ever in the 52 years of Universiade history, organizers said here on Thursday.

"With just one day to go, I can say Shenzhen Universiade would be the biggest in history," said Huang Guoqiang, a spokesman of the Shenzhen Universiade.

Huang said a total of 306 events from 24 sports would be held, making the largest number of events in Universiade history. 11,901 athletes and officials from 152 delegations had confirmed their arrival until Thursday.

According to the Universiade organizing committee, China, Russia and Japan are the three leading delegations in the number of athletes. Also some countries including France and the next Olympics host Braitan had formed their largest delegation in their Universiade history.

"It will be London's turn to be the host of the Olympics less than a year later. The team's participation in the Universiade will further strengthen the already excellent ties Britain enjoys with Shenzhen," said Alastair Morgan, the Consul-General of the British Consulate-General at Guangzhou.

Huang said a "great number" of correspondents from both home and abroad would cover the upcoming Universiade. According to the latest data from the organizing committee, a total of 3,156 journalists from 331 media organizations around the world had registered to cover the Games.
