After officiating at the opening ceremony, Mr Leung and his wife toured the expo.
They sampled the delicacies at some food stalls and bought items including electronic books, Chinese cakes, dried fruit and potted plants.
The Chief Executive also stopped by a social enterprise booth and called on people to support these businesses.
There are more than 400 exhibitors and 800 outdoor booths at the expo, which runs until January 4.
