Summary

German authorities have arrested a U.S. citizen, identified as Martin D., in Frankfurt on suspicion of offering U.S. military intelligence to China.

Martin D., who recently worked for the U.S. armed forces in Germany, allegedly reached out to Chinese government agencies this year, offering sensitive military information.

His arrest is part of an uptick in espionage cases involving China in Germany.

Last month, a Chinese woman, Yaqi X., was detained for passing logistics data on military cargo and personnel to Chinese intelligence, while another Chinese national, Jian G., linked to a far-right German politician, faces separate espionage charges.
