There are rising concerns about China’s new embassy in Europe, with a security expert cautioning that it could serve as a surveillance tool for the entire continent. Plans for the embassy reveal a discreet room near crucial cables, raising alarms.

Recently disclosed documents highlight the existence of a secretive chamber situated in the building’s northwest corner. This room is located just a few meters from an essential fibre-optic cable network, which carries financial information between London’s financial hubs, the City and Canary Wharf.

Professor Anthony Glees, an authority on intelligence and security from the University of Buckingham, emphasized the potential risks of allowing China to advance with this project.

In a conversation with Nick Ferrari on LBC’s Breakfast show, he remarked, “The proximity of these rooms to the cables is concerning, as they could be tapped effortlessly.”

Furthermore, he pointed out that the building includes heating systems capable of supporting large servers, suggesting that the facility could not only monitor UK activities but also act as a central intelligence station for Chinese operations throughout Europe.

Professor Glees also voiced unease over the complex’s vast size, implying it might be used to intimidate or detain dissenters. He referenced a 2022 incident in which a Hong Kong democracy activist was forcibly taken into the Chinese consulate in Manchester and assaulted, illustrating potential risks.

His warning coincides with a letter from a group of Labour MPs who are urging Sir Keir Starmer to reject China’s plans – which could be greenlit as soon as this week. 

In a letter to Communities Secretary Steve Reed, they raised security concerns and said the embassy could be used to ‘step up intimidation’ against dissidents.

The MPs, including Sarah Champion – who is a member of parliament’s Joint Committee on the National Security Strategy, said concerns about the proposal are ‘significant and unresolved’. 

They cite ‘the recent track record of Chinese espionage cases, interference activities, and issuing of bounties against UK-based Hong Kongers’, as well as ‘the fact that this embassy would sit above sensitive infrastructure critical to both the UK’s economic and national security’. 

The secret room seen in the plans is triangular and measures up to 40 metres across and 2-3 metres deep. 

It includes at least two air extraction systems, according to The Telegraph, seemingly indicating it could house heat-generating equipment such as high-tech computers.

It is part of a network of 208 secret rooms – a majority of which are hidden from the public in planning proposals – beneath Beijing’s ‘super-embassy’, which is set to be built on the site of the Royal Mint pending approval from Sir Keir Starmer.

MPs from across the political spectrum have urged the Government to reject China’s application for a new embassy on the site of the former Royal Mint, citing security concerns.

Downing Street is said to have proposed that the Prime Minister approves the plans before he visits China later this month in a bid to smooth over relations with President Xi Jinping following a series of planning delays.

But there are fears the new embassy could be used as a ‘spy centre’, with some critics raising concerns that China could tap into the cables and eavesdrop on key information.

Documents also reveal that the outer wall of the chamber, lying directly next to the cables, would be demolished and rebuilt, further fuelling fears they could be tapped. 

Security expert Professor Alan Woodward said this was a ‘red flag’ and having the cables so close to the building would be an ‘enormous temptation’ for China. 

Last year, The Mail on Sunday revealed that planning documents for the embassy included ‘spy dungeons’ – two suites of basement rooms and a tunnel, with their purpose redacted for security reasons.

Diplomatic sources also revealed that a proposed ‘spy campus’ will provide on-site accommodation for more than 200 intelligence officers at the embassy. 

A row has rumbled on about the planned mega embassy since 2018 when China bought the 215,280 sq ft site for £255million from the Crown Estate.

Security fears were immediately raised over the land’s proximity to sensitive underground communications in the Square Mile.

The cables along Mansell Street, which belong to companies including BT, Colt Technologies and Verizon, carry communications to and from financial institutions in the City of London.

They sit directly between financial hubs in the City and Canary Wharf and close to three major data centres, including the Stock Exchange. 

Those who have fled Hong Kong’s Chinese regime also fear the huge embassy would be used as a base to hunt them down. 

Copies of plans with redacted basement rooms revealed in The Mail on Sunday also heightened fears about China’s plans for the complex.

It revealed that planning documents for the controversial embassy include ‘two suites of anonymous unlabelled basement rooms and a tunnel’, with their exact purpose ‘redacted for security reasons’.

China has dismissed claims the embassy could be an espionage hub, while BT told the Telegraph it had ‘robust security measures in place’ and worked with the Government to protect its assets.

Shadow justice secretary Robert Jenrick said in a post on X that the unredacted plans were ‘shocking’, adding: ‘No one committed to our national security could possibly sign this off. But Kowtow-Keir will.’
