According to reports, the suspect worked since the 1980s for the Hanns Seidel Stiftung, a political research foundation named after a former chairman of the conservative Christian Social Union (CSU) of Bavaria. The Munich-headquartered foundation is the informal think-tank of the CSU, which is the Bavarian arm of German Chancellor Angela Merkels’ Christian Democratic Union.

As part of his job, Klaus L. traveled frequently to countries in Africa, Asia and Europe, as well as former Soviet states. It is also believed that, for over 50 years, he had worked as a paid informant for the German Federal Intelligence Service (BND) —Germany’s foreign intelligence agency, which is equivalent to the United States Central Intelligence Agency. According to a government press statement, Klaus L. would provide the BND with information relating to his foreign travels, conference attendance and other “certain issues” of interest to the spy agency. In return, the BND allegedly funded some of his travel and conference expenses, and provided him with a regular stipend.

But in the summer of 2010, Klaus L. was allegedly approached by Chinese intelligence during a trip to the city of Shanghai. According to German counterintelligence, he was persuaded by the Chinese to cooperate with Chinese intelligence operatives, and did so until the end of 2019. In November of that year, German police searched his home in Munich, as part of an investigation into his activities. In May of this year, Klaus L. was charged with espionage and on July 5 he was formally arrested.

Interestingly, Klaus L. does not deny that he provided sensitive information to China. He argues, however, that he informed his BND handler about his contacts with the Chinese, and that these were known to German intelligence. He therefore claims that his Chinese contacts were part of a German counterintelligence operation targeting the Chinese government. His trial is scheduled for this fall.
