Chinese investor Fujian Grand Chip Investment Fund (FGC) was supposed to have sealed deal between German semiconductor equipment manufacturers Aixtron on Oct. 6, 2016, but was abruptly called off by the German Economic Ministry this Monday over unspecified national security issues.

U.S. intelligence services warned Germany that a Chinese takeover of German semiconductor manufacturing equipment maker Aixtron could give Beijing access to technology for military purposes, reported German paper Handelsblatt on Wednesday.
