The two-day 10th Belt and Road Summit will be held at the Convention and Exhibition Centre on Wednesday and Thursday.
Writing on his blog on Sunday, Chan said the speakers at the summit will discuss business opportunities created by the initiative in different sectors including investment, innovation, infrastructure, logistics and professional services.
Hong Kong has been actively contributing to the initiative, which has benefited participating countries and regions since it was launched in 2013, he added.
Chan also said he visited two historic sites related to the War of Resistance on Saturday.
The government has gathered information on more than 40 war resistance-related sites, and conducted repair and maintenance works at these places, he said.
