The judicial review targeted a decision made by the Secretary of State for Housing, Communities and Local Government on Jan. 20, 2026, which granted planning permission and listed building consent for the diplomatic complex.
The RMCRA said that they intend to appeal the High Court's ruling, hoping to take the case to the Supreme Court.
The association represents roughly 100 households and businesses. They fear that the site poses an espionage threat, will be used to enforce "draconian" Chinese laws in the UK and target dissidents, causing disruption to local residents.
In addition to local residents, the plan has faced strong opposition from human rights groups, members of the Conservative Party, and others.
In a summary of the ruling, the judges stated that the government had "fully and fairly" considered the security concerns raised by local residents and deemed the planning permission "lawful."
The judges held that the government had given full consideration to national security as well as other potential issues the Chinese embassy might pose to nearby residents.
The judges said that the court's ruling concerned the lawfulness of the government's decision, rather than the merits of approving the embassy itself.
Ever since China purchased the site in 2018 for $340 million (£255 million), its embassy construction project has been plagued by controversy, including warnings issued by the United States.
However, UK intelligence agencies stated that the relevant security risks could be mitigated.
In January, the UK Labour government approved the plan—a move seen as part of an effort to mend relations with Beijing. The approval came on the eve of Prime Minister Keir Starmer’s visit to China, during which he expressed hope to expand bilateral investment and cooperation opportunities following years of chilly relations.
British planning records show the projected Chinese embassy will top 50,000 square meters. This massive footprint would surpass the 12-story U.S. complex nearby, making it the largest embassy in London and likely all of Western Europe.
