Northern Metropolis

The Northern Metropolis is a planning area in Hong Kong, located in northern New Territories as part of Northand Yuen Long Districts. It is envisioned as an integrated living and economic region, focused on integrating Hong Kong more closely with the Guangdong–Hong Kong–Macau Greater Bay Area, particularly with Shenzhen.
The centrepiece of the new development is planned to be the San Tin Technopole, an innovation and technology centre which will include the Hong Kong–Shenzhen Innovation & Technology Park located on the Lok Ma Chau Loop; and an innovation and technology park in San Tin.
In March 2023, Regina Ip said that the Northern Metropolis project should be prioritized over Lantau Tomorrow Vision; John Lee then responded by saying both projects would move ahead simultaneously without the need to prioritize one over the other. In April 2023, a survey showed that only 6% of Hongkongers supported Lee's idea to build both simultaneously.
In July 2024, it was revealed that 80% of submissions from the public opposed the plan to build the Technopole due to construction on wetlands.
In 2025, Financial Secretary Paul Chan Mo-po said the Northern Metropolis should refer to Xiong'an New Area for planning, construction and attracting industrial investment.

Villagers

In August 2023, Hong Kong Secretary of Technology and Innovation Sun Dong said that he had "suffered a lot of pressure" from New Territories rural leader Kenneth Lau, over Lau's insistence to integrate villages into the San Tin Technopole plan.
In August 2024, a 29-year-old villager filed a lawsuit against the government's plans to reclaim some villager land for the project, saying that the land was protected under the small house policy.
