Chief Executive John Lee said on Tuesday Hong Kong will seize every opportunity to help social media influencers show the city to the world.

Lee was speaking after YouTube megastar IShowSpeed's visit here last week.

The live streamer drew crowds of fans and chaos as he made his way to Causeway Bay, Ocean Park and the Temple Street night market on Friday.

Speaking before the weekly Executive Council meeting, Lee said the Tourism Board had reached out to the YouTuber but didn't hear back from him.

"This KOL [key opinion leader] has many followers, he has many fans, so I'm sure we all take very seriously any opportunity to publicise Hong Kong," he said.

Lee also called on different sectors of the community to welcome and support influencers coming to the city.

"I see there were hotels, restaurants, public transport operators which provided Speed and other KOLs assistance in their broadcasting," he said.

"So if anyone wants to promote Hong Kong, please do our best to help them because Hong Kong is our home."

Asked about his assessment of Super March, Lee said the series of mega events attracted overseas tourists and boosted the hotel and catering industries.

He said more mega events are lined up for April, including the first-ever World Internet Conference Asia-Pacific Summit to be held in Hong Kong.
