In a blog post today, Chan mentioned he visited representatives, including government officials, fund enterprises managers, and leading merchants in Saudi Arabia and Bahrain last week, noting the Greater Bay Area shows huge appeal to the Middle East.

Chan added many executives of international financial enterprises have shown anticipation for the upcoming Global Financial Leaders' Investment Summit, which is scheduled to be held in Hong Kong this Wednesday.

"I will return to Hong Kong for the summit in person or via video meeting at the earliest opportunity," said Chan, citing that his health conditions had improved.
