BERLIN — The German Bundestag’s Parliamentary Supervisory Committee meets in private. It is rare for any details of the discussions between delegates, who oversee the activities of the German intelligence services, to leak to the outside world.

But in the past week, the Committee very deliberately broke its usual vow of silence. In a public statement, delegates called for stricter regulations for government employees whose jobs relate to matters of security, when they make the move to the private sector.

Above all, the committee said that engaging in work for a foreign power should “automatically qualify as a breach of the obligation to secrecy for civil servants with jobs related to matters of security."

One reason for the unusual announcement: growing concerns about Chinese efforts to recruit former German military and intelligence officers.

In security circles, the word is that the Beijing regime is showing a marked interest in operational and tactical information from the West. Beijing is looking to recruit NATO pilots, with the aim of honing fighting techniques against Western military planes and helicopters. This recruitment often happens via foreign flying schools.
