The two men have been identified in media reports only as “Henri M.” and “Pierre-Marie H.”. They are both reportedly former employees of France’s Directorate-General for External Security, known as DGSE. The service operates as France’s equivalent of the United States Central Intelligence Agency. A third suspect, “Laurence H.” is reportedly the wife of Pierre-Marie H., and stands accused of “concealing property derived from espionage on behalf of a foreign power, which is likely to harm the fundamental interests of the nation”.

According to reports in the French media, Pierre-Marie H. was arrested in late 2017 while transiting between flights at Zurich airport. He was found to be carrying on him a large amount of undeclared cash, which was reportedly given to him by his Chinese handler, following a meeting on “an island in the Indian Ocean”. He is currently free on bail.

The DGSE appointed Henri M. in the Chinese capital Beijing as its station chief. He was allegedly listed as the second secretary at the French embassy there. However, he was recalled to Paris less than a year following the start of his foreign assignment, after he was found to have an affair with the female interpreter of the ambassador. The interpreter was reportedly a Chinese citizen. In 2003, following his retirement, Henri M. reportedly relocated to China, where he married the interpreter and settled in the southern Chinese island of Hainan.

Like Pierre-Marie H., Henri M. was arrested in late 2017, reportedly after a lengthy surveillance operation by French counterintelligence, which lasted several months. Both men are accused of “delivering information to a foreign power” and by doing so “damaging the fundamental interests of the French nation”. French officials have described the cases of the two men as “extremely grave”. The trial will take place in a special court that will convene behind closed doors. The verdict is due to be announced on July 10. If convicted of all charges against them, the two men face 15 years behind bars.
