China’s secret service has accused MI6 of turning two Chinese state workers and recruiting them as spies, Ednews informs via The Guardian.

The ministry of state security (MSS), which has responsibility for China’s intelligence gathering and secret police, said on Monday it had uncovered the “major espionage case” involving a husband and wife both working in “core key units” of a Chinese state agency.

The accusation, which was written about by Chinese state media outlets, follows several high-profile cases of alleged Chinese espionage in Europe, including in the UK, Germany and Belgium.

In a post on its WeChat account, the MSS said the husband, surnamed Wang, had been recruited first when he travelled to the UK in 2015 as part of an exchange programme. After Wang arrived “MI6 deliberately arranged for relevant personnel to take special care of him”, the MSS said. Wang was invited to dinner gatherings and offered visits and tours, as MI6 worked “to understand his character weaknesses and interests”, it alleged.

It said they took advantage of Wang’s “strong desire for money”, and arranged for him to give “consulting services” before convincing him to return to China and spy for the British government.

Through Wang the British spies then recruited his wife, surnamed Zhou, it said. Wang had been initially hesitant but “couldn’t withstand the British repeated persuasion, enticement and even coercion”, it said.

“He and his wife together became British spies.”

The MSS said the case was under further investigation but did not say if the couple had been detained or charged.

In January it accused MI6 of recruiting a national from a third, unnamed, unnamed country to spy on China, instructing him to “use his public identity” to collect information during multiple trips to China from 2015 onwards.
