Around 18,000 tickets will be made available over the six competition sessions at the Championships, which will be held at Nanjing’s Cube Indoor Athletics Facility from March 13 to 15.

The tickets will range in price from RMB50 (£5/$7/€6) to RMB600 (£66/$86/€77), but will not be assigned to a particular seat.

Instead, ticketed spectators can be seated freely anywhere in the ticket's designated zone.

Online reservations are set to begin at 10am local time on January 16 at 10am on the official website of the Championships.

Wenkor Ticketing has been selected as the general ticketing agent for the event.

Wu Yahui, assistant director for marketing development at the Organising Committee, also introduced Cedar, the official Nanjing 2020 mascot, at a press conference in the Chinese city,

"Created by a design team headed by young artist Zhang Qingfeng, Cedar represents a lively, confident figure, with its head held high, likened to an athlete eager to take on challenges," organisers said.

"The year 2020 is the Year of the Mouse in the Chinese lunar calendar, the inspiration behind the snow squirrel design.

"Its name is taken from Nanjing's symbolic tree.

"Organisers received 827 mascot design submissions from around the world."
