UK Approves Chinese “Mega Embassy” in London Amid Security Warnings and Legal Threats

The U.K. government has approved China’s plan to build a vast new embassy at Royal Mint Court near the Tower of London, despite warnings from intelligence agencies and opposition from MPs and local residents. The 20,000–22,000 square metre complex will consolidate seven Chinese diplomatic sites into a single location, including over 200 operational rooms and more than 230 residential units for staff, with 208 underground rooms and a hidden chamber. While MI5 and GCHQ have confirmed that risks to national security can be mitigated, critics argue the embassy could become a hub for espionage and intimidation of political exiles. Residents’ associations have announced plans for a judicial review, which could delay construction, and the decision is widely seen as paving the way for Prime Minister Keir Starmer’s forthcoming visit to Beijing, highlighting the complex balance between diplomatic engagement, security, and domestic opposition.
