Lantau Tomorrow Vision

Lantau Tomorrow Vision (Chinese: 明日大嶼願景), also known as the Kau Yi Chau Artificial Islands, is a postponed development project in Hong Kong which proposes creating the city's third central business district (CBD) by constructing large artificial islands through massive land reclamation. These islands, with a proposed total area of about 1,700 hectares (4,200 acres), would be located near Kau Yi Chau and Hei Ling Chau of the eastern waters of Lantau Island.

The project was first suggested in 2014 by the city's chief executive, Leung Chun-ying, before being formally proposed in 2018 by his successor, Carrie Lam, in her second policy address. It has been met with controversy and opposition due to environmental concerns and also its high cost of an estimated HK$580 billion (US$73.8 billion), amounting to half of the city's fiscal reserves. In February 2024, the city's financial secretary said the project has been postponed after financial considerations, but insisted that it would not be cancelled. Secretary for Development Bernadette Linn stated in September 2025 that the current term government would not proceed with the project in its term, saying that it did not have the "necessary conditions" for it to be carried out and that the government had not yet "formulated a timetable" for the project.
