We reported on a negative view from the German authorities on the potential acquisition of Aixtron by China’s Fujian Grand Chip Investment Fund (FGC) (Aixtron Sale to China Blocked). The deal was also viewed negatively by US authorities on ‘security’ grounds, but the companies have appealed directly to President Obama, who is due to give a decision in the next few days. The companies have used the direct appeal process which has only been used twice before, in 1990 and 2012.
