Fencing champion Edgar Cheung and double swimming silver medallist Siobhan Haughey have been named as the flag bearers for the Hong Kong, China team at the Olympic opening ceremony later this week.

The SAR Athletes will join thousands of other competitors in a unique ceremony taking place on the River Seine in Paris, and winding past some of the most famous landmarks in the French capital on Friday.

Speaking ahead of their departure to Paris, the Chef de Mission of the SAR delegation, Brian Stevenson, called on Hongkongers to back the athletes.

"I look to the athletes to perform their best, and of course the best for each athlete differs, but I'm talking about their personal best. If they can achieve that, you cannot ask for more than that, other than that bit better than even their best," he added.

"I'll be satisfied if all the athletes have given their very best performance and we know their records and what they can achieve."

Cheung, who was the city's flag bearer at the Tokyo Olympics, becomes the first Hong Kong athlete to be picked for the honour in successive Games.

Stevenson also confirmed air-conditioners will arrive at the Olympic village on Tuesday, admitting the units were arriving later than scheduled because of security reasons.

The SAR is one of a number of delegations that decided to install air conditioners at the athletes' rooms, despite claims by the Paris organisers that a geothermal cooling system would keep temperatures at the newly-built village reasonable.
