President Xi Jinping on Saturday urged more effort to ensure smooth progress on major infrastructure projects in Hong Kong as he inspected the construction sites of the Hong Kong section of the Hong Kong-Zhuhai-Macao Bridge and third runway at the city's airport.

The inspections were the president's last stops before ending his three-day trip in the special administrative region to celebrate the 20th anniversary of Hong Kong's return to the motherland.

At the bridge construction site Xi expressed appreciation for all those who had contributed to the project.
