China said Wednesday a staffer at the British Consulate in Hong Kong has been given 15 days of administrative detention in the city of Shenzhen for violating a law on public order.
At a daily briefing Wednesday, Foreign Ministry spokesman Geng Shuang said the case was “not a diplomatic issue.”
He said the man had violated regulations on “Punishments in Public Order and Security Administration,” but gave no further details.
The British Foreign Office has said it is “extremely concerned” about its staff member, identified by local media as Simon Cheng Man-kit, a trade and investment officer at the Scottish Development International section of the consulate. The reports said he attended a business event in Shenzhen on Aug. 8 but never returned to neighboring Hong Kong despite plans to do so the same day.
It is unclear whether the man possessed a diplomatic passport. Geng said he was a Hong Kong resident and not a U.K. citizen.
Public order and security infractions are generally minor — for instance, fighting on the street — and result in administrative rather than criminal punishments. The maximum penalty for such transgressions is 15 days in detention.
The seizure of a consular staffer of any status or rank is highly unusual. Despite Beijing’s declaration of a “golden era” in Sino-British ties, relations between the countries have grown tense in recent months amid pro-democracy protests in Hong Kong, a former British colony.
“Regarding the series of words and deeds by the British side recently on Hong Kong-related issues, we have repeatedly lodged solemn complaints with the U.K.,” Geng said, adding that China urges Britain to “stop meddling in Hong Kong affairs.”
Hong Kong Senior Police Supt. Kong Wing-cheung said Tuesday that Hong Kong law enforcement agencies were not notified about the case by mainland Chinese authorities under a mutual notification arrangement set up for such cases.
