China's mega embassy plan is deeply alarming. The secretive basement with redacted details suggests the intended purpose of surveilling and interrogating dissidents. The U.K. would never have given Stalin such a fortress in 1980, so why would it hand one to Xi's aggressive regime? Such a move would only threaten British and Western security and must be rejected at all costs.
China's embassy plans represent standard diplomatic practice under international law, with redacted areas routine when handling classified information. These security concerns are nothing more than politically motivated attempts to fuel anti-China sentiment. The U.K.'s paranoia stems from its own espionage activity and is not an honest reflection of Chinese intent.
