London has become the focal point of intense public and political opposition to China’s proposed new embassy as the United Kingdom government prepares to decide whether to approve plans for the sprawling complex by January twentieth.

Hundreds of protesters — joined by senior opposition figures — gathered near the former Royal Mint Court site close to Tower Bridge to voice concerns that the development could pose national security and surveillance risks, particularly given its proximity to sensitive infrastructure and communications networks.

The proposed embassy — covering about twenty thousand square meters and set to be the largest in Europe — has sparked broad unease among lawmakers and activists, who argue it could be used as a base for espionage and for intimidation of Chinese dissidents living in the UK. Many demonstrators carried placards and chanted against the scheme, describing it as unwise and unnecessary amid rising tensions between London and Beijing.

Britain’s main opposition leader joined demonstrators in urging the Labour government to reject the application, framing the decision as a matter of national sovereignty and security.

Critics have pointed to recent alerts from domestic intelligence services about foreign interference and recruitment efforts targeting lawmakers as evidence of heightened risks associated with the project.

Some Members of Parliament from both Conservative and Labour ranks have underscored concerns that underground facilities near the site could provide undue access to data links and compromise sensitive information.

Despite the protests and political pressure, UK security agencies including MI5 and MI6 have reportedly not raised formal objections to the embassy plan, and government officials have stressed that the planning process is independent and quasi-judicial.

Prime Minister Keir Starmer’s administration has maintained that protecting national security is paramount while also emphasizing the importance of diplomatic engagement with China.

Approval of the project could cement momentum for Starmer’s planned visit to Beijing and reset bilateral ties, but opponents say that endorsing the embassy would send the wrong signal at a time of growing geopolitical competition.

The government is expected to announce its final decision on or before the January twentieth deadline, closing a chapter on a contentious debate that has lasted years and captivated both local communities and national policymakers.
