More than 900 artifacts from the Palace Museum in Beijing will be displayed in the 13,000-square-metre space, which spans seven floors and houses nine themed galleries.

Many of the items on loan, including 166 "grade one" national treasures, are being exhibited for the first time in the city, alongside over 100 works on loan from local museums and cultural institutions, with the aim of showcasing imperial life and promoting Chinese culture.

The museum is also displaying 13 pieces of art from the Louvre Museum in France in an effort to highlight China's cultural exchanges with other parts of the world.

Construction of the HK$3.5 billion (US$446 million) project began in March 2019 and ended in December 2021.

Speaking at an opening ceremony held on June 22, Lam said the museum should work to promote Chinese culture to an international audience.

"The opening of the HKPM today is just the beginning. It bears an important responsibility and shoulders the mission of the times," she added.
